When Our Land Dries Out: Finland's Coming Drought Chain and Its Consequences 2026–2029
This article is based on public data from the Finnish Meteorological Institute, SYKE, the Natural Resources Institute Finland (Luke), the National Emergency Supply Agency, Copernicus Climate Change Service, NOAA, FAO, and numerous international research institutions. Every claim is verifiable through source references. The article takes no position on the ultimate causes of these phenomena — for that, you can read our earlier article, When the Heavens Close. This article describes mechanisms, measurement results, and their consequences.
I. What Is Happening Right Now
As a recap from our earlier article.
In February 2026, Finland finds itself in a situation without precedent in the modern measurement record.
January 2026 was 3–10 degrees colder than normal and received only a quarter of its usual precipitation. Multiple measurement stations recorded their driest January ever. At Enontekiö airport, −44.3 °C was registered — the coldest reading in Finland in the entire 21st century. In February, Vihti recorded −32.8 °C — a new winter record for southern Finland. Meteorologists summed up the situation in a single sentence: "The extreme cold is made possible by dry, windless weather." Dry. No rain. No snow.
This is not an isolated unusual winter. It is part of a chain that began in 2024. Groundwater levels have dropped 40–90 centimetres below normal — a level matching the worst readings of the 2018 drought crisis. In 2018, however, that deficit followed a single dry summer. Now the same shortfall has built up through multiple consecutive dry periods, and spring's critical recharge season lies ahead with no guarantee of sufficient snowmelt.
Hydrogeologist Bertel Vehviläinen of the Vesi.fi service has stated the principle that is central to this article: groundwater recovery takes at least as long as the deficit took to develop. If the deficit built up over two years, recovery requires at least two years of normal or above-normal precipitation. In Finland's aquifers — particularly small moraine formations where less than 10% of precipitation infiltrates — memory is long. In esker formations, where the water table may lie at depths of up to 50 metres, recovery can take over four years.
The situation is not limited to Finland. Europe experienced its coldest January in 16 years. Alpine snowpack was half of normal. In Italy's Adige river basin, snow water equivalent was 67 per cent below normal. In the United States, January was the 11th driest in 132 years of records, and western snowpack fell to its lowest level in the satellite era. The Colorado River's upper basin snow water equivalent dropped to 36 per cent of the median — the weakest since 1986.
All of these phenomena are linked to the same atmospheric structure: a polar vortex disruption that began in November 2025 and continues still. It is no coincidence that all of this is happening at once. These are different manifestations of the same mechanism.
II. Why the Heavens Have Closed
To understand why Finland stands on the threshold of drought, one must understand four atmospheric mechanisms and how they chain together. None of them is exceptional in isolation. Their simultaneous occurrence and self-reinforcing interaction is what makes the situation severe.
The first link: polar vortex disruption
At roughly 20–50 kilometres altitude above the Arctic, a vast air current — the polar vortex — circulates during winter. When it is strong and stable, cold air stays in the Arctic and Finnish winters are mild and wet. When the vortex is disrupted or splits, a phenomenon known as sudden stratospheric warming (SSW) occurs: cold Arctic air spills southward and warmer air rises northward. Weather patterns shift for weeks or months.
According to NOAA statistics, significant SSW events have occurred at an average rate of 6.4 per decade since 1958. They are not rare, but their probability varies sharply depending on the state of the rest of the atmosphere. During El Niño winters, the frequency of SSW events is nearly double that of neutral winters. When this coincides with the easterly phase of the QBO (another atmospheric oscillation), SSW probability rises further still.
In November 2025, the first polar vortex disruption began. In December, the vortex split. In early February 2026, a second disruption began. This chain explains Finland's record cold, and it explains why it came as dry, windless, snowless frost.
The outlook for winter 2026–2027 darkens the picture further: La Niña is breaking down rapidly and El Niño is the most likely single state from July–September 2026 onward (IRI forecast: 48–51% probability). Combined with a likely easterly QBO phase, the probability of an SSW event during winter 2026–2027 is estimated at 60–70%. This means a similar cold, dry winter pattern is more likely to repeat than not.
The second link: negative NAO and dry cold
Following an SSW event, the atmospheric signal propagates downward into the troposphere, typically producing a negative North Atlantic Oscillation (NAO). A negative NAO means, in practical terms for Finland, that the moist airflow from the Atlantic weakens or ceases. Normally this flow brings Finland its winter precipitation — the snow and rain that maintain soil moisture and feed groundwater. When it stops, what remains is dry cold: frigid air without precipitation.
This is exactly what has happened during the winter of 2025–2026, and it is the most probable scenario for winter 2026–2027.
The third link: soil moisture feedback
At this point the mechanism becomes self-reinforcing, which is why it deserves particularly close examination.
Normally, Finland has what is called an energy-limited climate: moisture is generally sufficient and evaporation is constrained primarily by solar energy. This means soil moisture does not normally affect precipitation levels significantly. Finland is not Central Europe, where dry soil can measurably reduce local rainfall.
In 2018, something exceptional happened. Dirmeyer (2021, AGU Advances) demonstrated that Northern Europe, including Finland, "transitioned to an unprecedented state where it became a land-atmosphere coupling hotspot." As the soil dried sufficiently, evaporation collapsed, solar energy heated the ground surface directly without the buffering effect of moisture, and temperatures rose to exceptional levels. This is the same phenomenon that produces Central European heatwaves, but it activated at Finland's latitudes for the first time in observational history.
Schumacher, Keune, Dirmeyer & Miralles (2022, Nature Geoscience) analysed the 40 largest recent global droughts and demonstrated that dry soil reduces evaporation, which reduces atmospheric moisture, which reduces downwind precipitation. A self-feeding cycle emerges. Benson & Dirmeyer (2021) identified a "tipping point" for soil moisture below which the atmosphere becomes hypersensitive to further drying: evaporation collapses, temperatures rise sharply, and drought begins to feed itself.
It is important to state plainly what this means and what it does not. The vast majority of Finland's precipitation — over 90 per cent — comes from external sources, primarily the Atlantic. Local recycling (evaporation from land → rainfall on the same area) accounts for only 3–8 per cent. Soil moisture feedback therefore does not "shut off rain entirely." Rather, it is a conditional amplifier that activates under exceptional conditions, making hot periods hotter and dry periods drier. It is not a constantly active mechanism but a threshold phenomenon: normally dormant, but powerful once triggered.
The fourth link: blocking patterns
When the soil is dry and atmospheric moisture transport is disrupted, conditions favour stationary high-pressure areas — so-called omega blocks. These are large high-pressure zones that prevent the normal passage of weather fronts and lock the same weather pattern in place for weeks. The 2018 Scandinavian heatwave was the product of precisely such a block.
Here it is important to be honest about what the data says and what it does not. There is no statistically significant evidence of a long-term frequency trend in blocking patterns. A 110-year analysis (1901–2010) published in Springer's Climate Dynamics journal found no significant trend in the prevalence of Northern Hemisphere blocking. This article does not claim that blocks have become more frequent. Instead, the argument rests on the fact that ENSO-driven circulation anomalies and SSW→NAO pathways produce blocks under specific conditions — and those conditions are probable in the coming years.
The chain summarised
The four mechanisms form a chain in which each link reinforces the next:
Polar vortex disruption brings a cold, dry air mass to Finland. A negative NAO cuts off Atlantic moisture transport, so the cold arrives without snow or rain. Dry soil activates a feedback loop that amplifies summer drought and heat. Blocking patterns lock the pattern in place.
This chain is not theoretical. Every link in it has been measured and documented during the winter of 2025–2026. The question is not whether it can happen. The question is how long it will continue.
III. The Ground Freezes: What Deep Frost Does to Finland's Fields
If the previous chapter described what is happening in the sky, this chapter describes what is happening in the ground — and that, ultimately, is what decides whether Finland can feed itself from its own fields.
Snow is the field's blanket — and it is missing
Any Finn who has even dabbled in gardening knows that snow protects plants from frost, but few realise how dramatic the difference is. A snow layer of just 10–15 centimetres insulates the ground so effectively that frost penetrates only 10–40 centimetres. Without snow, frost reaches far deeper: at the Mietoinen measurement station in Southwest Finland, frost extended to 74 centimetres by the end of January in a low-snow winter and to nearly one metre in February. At the Angeli station in Inari, where no snow accumulated, frost reached 170–190 centimetres and did not fully thaw before July.
Finland's building codes tell the same story from another angle: the design values for frost depth in snowless ground are 180 centimetres in southern Finland and 260 centimetres in the north. These figures are intended for foundation design, but they also reveal how deep frost can penetrate when snow provides no protection.
Physics explains why dry soil is especially vulnerable to deep frost. According to the Stefan equation, frost depth is inversely proportional to the square root of soil moisture. In practice, this means that if soil moisture is halved, frost advances 41 per cent deeper. If moisture drops to one-third, frost advances 73 per cent deeper. Dry ground freezes faster, deeper, and thaws more slowly than moist ground.
The Halola experiment — a warning from the earth
In 2014, Yle reported on an experiment by the Agrifood Research Centre (MTT, now part of Luke) at Maaninka. Research Professor Perttu Virkajärvi led an experiment in which snow cover was manually removed from test plots. The result was dramatic: frost advanced to a depth of two metres, all vegetation died, and the ground did not fully thaw before midsummer.
This was not an exotic laboratory setup. It was a simple demonstration of what happens when there is no snow — and it describes precisely the situation toward which Finland's fields are heading as winters continue dry and snowless.
Sowing is delayed — and every week costs
Finland's spring sowing normally begins in late April in southern Finland and early May in Ostrobothnia. Sowing requires that frost has thawed to sowing depth and that soil temperature has risen to at least 4–5 degrees. Oats tolerate slightly cooler conditions; peas and broad beans require over 6 degrees.
Sowing-date trials conducted at the Jokioinen research station during 1980–1984 (Rahkonen & Esala 1988) remain Finland's most important studies on the relationship between sowing time and yield. They showed that when sowing is delayed by three and a half weeks — from the beginning of May to the end of May — oat yields drop by approximately 170 kilograms per hectare per week, spring wheat by approximately 130 kilograms, and barley by approximately 75 kilograms. In percentage terms, this translates to roughly a four per cent loss for oats and a three to four per cent loss for wheat for every week of delay.
A critical additional finding comes from the ten-year study by Kivisaari and Larpes (1983) at Tikkurila: early-summer drought strongly amplifies the yield losses from late sowing, particularly on silty clay soils. This is precisely the combination — late sowing and dry summer — that the drought scenario produces.
Finland's growing season ranges from 100 to 180 days depending on latitude. Spring cereals require 90–110 days to mature and an accumulated temperature sum of 850–1,050 degree-days (above 5 °C). If sowing is delayed until mid-June, southern Finland has 90–100 days remaining — barely enough for the fastest barley varieties but insufficient for wheat. If sowing shifts to the turn of June and July, practically no Finnish spring cereal variety can mature before the autumn frost arrives. Yield losses at that point approach one hundred per cent.
There is surprisingly little precise Finnish research data on the relationship between frost depth and sowing delay. However, from forest soil studies (Repo et al.), it can be extrapolated that deep frost delays soil thawing by 1.5–2 months compared to normal. Engineering estimates suggest that frost thaws at approximately 1–2 centimetres per day under favourable conditions, though this varies significantly with soil type and moisture. As a rough estimate: 80 centimetres of frost in dry soil delays sowing by 3–5 weeks; 150 centimetres of frost by 6–10 weeks.
A delay of this magnitude has not occurred in modern Finnish agricultural history.
The destruction of winter crops and grassland
Sowing delay concerns spring cereals, but for winter crops — rye and winter wheat — the problem is different: they are already in the ground over winter, and without snow cover they are exposed directly to frost.
Peltonen-Sainio, Hakala & Jauhiainen (2011) analysed MTT's official variety trials from 1970–2006 and found that extreme overwintering damage can destroy up to 90 per cent of the harvest. The lethal temperature (LT50) for Finnish winter wheat varieties is approximately −15 to −20 °C; winter rye is more resilient, tolerating approximately −25 to −30 °C (Hömmö 1994). Without snow cover, ground surface temperatures can drop to −20 to −35 °C during severe cold spells. This means a 50–90 per cent winterkill risk for winter wheat and 30–70 per cent for winter rye.
The most severe situation, however, concerns forage grass. The foundation of Finland's livestock sector is approximately 700,000 hectares of grassland, from which silage is produced. Timothy, Finland's most common grass species, tolerates freezing to approximately −15 to −18 °C when fully hardened (Höglind et al. 2010). Meadow fescue is more sensitive, and red clover the most sensitive of all. Without snow cover, expected damage rates are 30–60 per cent for timothy, 50–80 per cent for meadow fescue, and 70–100 per cent for red clover.
Destroyed grass stands require complete reseeding, but newly seeded grass produces only 40–60 per cent of a mature stand's yield in its first year — and under persistent drought, seed germination itself is uncertain.
IV. Harvest Shrinks from the First Year to the Third
Baseline and normal variation
Finland's total grain harvest over the past 20 years has averaged 3.4–3.5 billion kilograms per year, ranging between 2.6 and 4.1 billion kilograms. Barley is the largest single crop at approximately 1.4–1.5 billion kilograms, followed by oats at approximately one billion (Finland produces about 12 per cent of the EU's oats), spring wheat at approximately 820 million kilograms, and rye at approximately 80 million kilograms — while domestic demand for bread rye is approximately 100 million kilograms per year.
The worst years in recent history have been 2021 (2.6 billion kilograms) and 2018 (2.7 billion kilograms), both caused by growing-season drought.
The lesson of 2018: the impact of a single dry summer
The 2018 drought is recent history's most important reference point, and its impacts deserve careful examination because they form the baseline for what a single dry summer does.
Wheat production dropped 38 per cent to 498 million kilograms. Rye collapsed 71 per cent to just 41 million kilograms. Oat yields fell 19 per cent to 819 million kilograms; barley 8 per cent to 1,329 million kilograms. Overall, the harvest was the smallest of the 21st century — a third below peak-year levels.
Regional variation was extreme. Southwest Finland, the heartland of Finnish grain farming known as the country's "breadbasket," suffered an estimated 30–40 per cent loss in per-hectare yield as its clay soils cracked from drought. Eastern and northern Finland, which received more rain, fared more moderately. Peltonen-Sainio et al. (2021) calculated that Southwest Finland loses 7–20 per cent of its average annual yield from early-summer drought alone over the long term.
Beyond quantity, quality collapsed. Only 65 per cent of the oat harvest met minimum quality criteria, and only 2 per cent reached export grade — compared to 47 per cent the previous year. Approximately 283 million kilograms of oats qualified only as low-grade feed or was effectively waste. Bread grain self-sufficiency dropped to 68 per cent.
Economically, 2018 was devastating. The profitability coefficient for grain farms fell to zero, meaning at least half of grain farmers received no return whatsoever on their labour and capital. Total agricultural losses exceeded 400 million euros. The profitability coefficient for dairy farms fell to 0.34. The average agricultural enterprise posted a 29,700-euro loss after production costs.
All of this happened after just one dry summer, preceded by normal soil moisture conditions.
Why the second and third years are worse than the first
Multi-year drought is not the same thing as a single dry year repeated. It is a qualitatively different phenomenon, and the reasons are biological, physical, and cumulative.
The first dry summer typically depletes soil moisture to a depth of 30–60 centimetres. The second dry summer penetrates deeper, to 60–150 centimetres, exhausting the moisture reserves that deep-rooted crops rely on in emergencies. The third dry summer meets soil with no reserves at any depth.
Soil organic matter — the dark, living layer that retains water and nutrients — begins to decompose as drought advances. Each percentage point lost in organic matter means a reduction of approximately 20,000 litres in per-hectare water-holding capacity. Finnish agricultural soils typically contain 3–6 per cent organic matter. Over four drought years, the estimated net loss is 0.3–0.8 percentage points — a level that can push weaker soils below the critical 3 per cent threshold where aggregate stability deteriorates significantly.
Australia's Millennium Drought (2001–2009) provides an international reference point. During the drought's intensification phase (2017–2019), Australian wheat production fell 73 per cent in 2018 and 63 per cent in 2019 compared to the long-term average. Van Dijk et al. (2013) made a critical observation: the reduction in rainfall was amplified in wheat yields by a factor of 1.5–1.7. In other words, a 10 per cent rainfall deficit produced a 15–17 per cent yield loss. Rice production collapsed by 98.9 per cent as irrigation water ran out. The sheep flock shrank from 120 million to 68 million.
This amplification factor explains why the impact of multi-year drought is not linear but accelerating. The first dry year is difficult. The second is worse than the first two combined. The third alters soil structure in ways that take years to repair even after the drought ends.
Finland's irrigation capacity offers no protection. Only 1–2 per cent of Finland's agricultural land — approximately 20,000–40,000 hectares — is irrigated, almost exclusively in vegetable and potato cultivation. Irrigation is not used for grain farming anywhere in Finland. Although Finland has 188,000 lakes, no canal systems or large-scale irrigation infrastructure have ever been built. Constructing such infrastructure for even 100,000 hectares would take years and cost billions of euros.
V. When Feed Runs Out: The Irreversible Crisis in Livestock Farming
This chapter addresses the single greatest vulnerability in Finnish agriculture: the impossibility of importing silage. It is a technical detail with enormous consequences, and understanding it is critical to the entire scenario.
Silage cannot be imported
Finnish livestock farming — dairy production in particular — depends on domestically produced silage. Annual silage production is approximately 8–9 million tonnes in fresh weight, two to three times the entire grain harvest. It is produced on approximately 470,000 hectares, entirely domestically.
This feed is not an internationally traded commodity. Its dry matter content is only 25–35 per cent, meaning that for every kilogram of nutrition, 2–3 kilograms of water are transported. It is too heavy, too perishable, and too bulky for international sea freight. Unlike grain, which can be loaded onto ocean-going vessels and shipped from the other side of the globe, replacing silage through imports is a logistical impossibility.
This means that the fate of Finland's cattle herd is tied directly to the domestic grass harvest. No international trade arrangement can substitute for this link. It is an absolute dependency.
The numbers reveal the scale
Finland has approximately 242,000 dairy cows on approximately 7,750 farms (an average of 52 cows per farm), approximately 64,700 suckler cows, approximately 988,000 pigs, and approximately 4.5 million laying hens. Dairy cows consume approximately 1.5–1.9 million tonnes of dry matter annually, divided roughly equally between silage and grain-based feed. Total feed grain usage is 1.6–2.0 million tonnes per year.
One distinctive feature of Finnish dairy production is that protein feed comes primarily from domestic rapeseed rather than imported soya. Pig feed contains approximately 6 per cent soya; poultry feed approximately 15 per cent. This reduces import dependency but does not eliminate the fundamental problem: silage is irreplaceable.
Sweden's 2018 experience shows how fast a crisis develops
In Sweden, the 2018 drought cut yields by 30–60 per cent below the five-year average. Total agricultural damage was estimated at 560–930 million dollars. Pastures failed completely and farmers were forced to feed winter stores to livestock in the middle of summer.
Demand for emergency slaughter overwhelmed abattoir capacity so severely that waiting times stretched to six months. A Swedish farmers' Facebook group called "Foderhjälpen" (Feed Aid) assembled emergency feed suppliers from Poland, the Netherlands, Germany, Britain, and the Baltic states: the group grew by 25,000 members in one week. The Swedish farmers' association warned: "Restoring the quality and size of the herd will take years."
This was the consequence of a single dry summer in a country where the previous year had been normal.
The timeline of adaptation and irreversibility
Different animal species adapt to feed shortages at different speeds. Broilers operate on a 35–40-day cycle and allow almost immediate adjustment. In pork production, fattening pigs are slaughtered at 5–6 months of age, and sow culling decisions take effect with a 4–6-month lag. Dairy herd adjustment is the slowest, because cows have the highest economic value and the longest replacement cycle: significant herd reduction takes 3–12 months from the onset of crisis.
It is precisely this slowness that makes dairy herd reduction irreversible. Replacing a culled dairy cow requires at least 2–2.5 years from calf birth to first milking and 3–4 years to full productivity. If the dairy herd is reduced by 20–30 per cent — from approximately 242,000 cows to 170,000–195,000 — recovery requires 5–7 years, assuming the remaining farms invest in expansion. But many farms will have closed permanently.
The research literature uses the term hysteresis for this phenomenon: production does not return to the same level even after the stressor is removed. The reason is not biological — more cows can be raised — but structural. When a farm closes, the milk collection route shortens and becomes less profitable. Dairy processing capacity is scaled down. Support services (veterinarians, inseminators, machinery contractors) diminish. An older farmer who quits during the crisis does not return. A younger one who never starts does not start later either. The American experience of dairy herd reduction during 2009–2011 confirms that recovery is measured in decades, not years.
If drought is simultaneous across Europe
In 2018, drought struck Scandinavia, Central Europe, and the Baltic states simultaneously. There is no reason to assume the next drought period will affect Finland alone. The Baltic states share Finland's synoptic weather pattern, making them unreliable as alternative feed sources. Potential emergency suppliers — North America, South America — require 2–4 weeks of sea transport, compete with global demand, and face the limitations of Finland's port infrastructure: Finland is normally a grain exporter, and bulk import capacity is limited. Baltic Sea ice restricts shipping from December to April.
VI. How Long the Buffer Lasts
Up to this point, the article has described how drought reduces production. This chapter answers the question every reader asks: "But surely we can't actually run out of food? We have stockpiles."
National Emergency Supply Agency reserves
Finland's National Emergency Supply Agency (HVK) maintains strategic grain reserves with a target level of at least six months of average domestic human consumption. When farm-level stocks and commercial and industrial inventories are added, the total buffer is sufficient for "slightly over one year" in a severe disruption scenario, according to HVK's estimate. The exact quantity is classified information.
The reserves are real and they are used. In spring 2022, HVK released 8,500 tonnes of spring seed grain from its reserves when the 2021 poor harvest had emptied commercial seed stocks. This happened after one bad harvest. In January 2025, HVK launched a new "Food and Water 2030" programme to develop long-duration crisis food supply — a signal that the current system was not designed for a multi-year crisis.
Six months, or "slightly over one year," is sufficient for a single crisis. It is not sufficient for a four-year drought in which domestic production is simultaneously 30–60 per cent below normal.
Supply chain vulnerability
One rarely discussed feature of Finland's food imports is their geographic concentration. Over 80 per cent of Finland's foreign trade travels by sea through the Baltic. Admiral Bo Österlund's research showed that replacing a single container ship would require approximately 1,000 trucks — a practically impossible volume given Finland's limited overland routes through Sweden and Norway.
Finland's most important food import countries are the Netherlands (1.2 billion euros), Germany (665 million), Sweden (over 500 million), Norway (over 250 million), and Spain (300 million). In normal years Finland imports very little grain, but after the weak 2021 harvest, grain imports in 2022 rose to 280,000 tonnes — 212 per cent above the previous year — primarily feed barley and maize from Germany, the Baltic states, and Poland.
If drought is simultaneous in Central Europe — as it was in 2018 — all of Finland's nearest import sources are themselves in trouble. This is not a hypothetical scenario. It happened four years ago.
Finland's self-sufficiency by product group
Finland's overall food self-sufficiency is approximately 80 per cent by volume, but this figure masks significant differences between product groups. Eggs exceed one hundred per cent (approximately 121%), potatoes and pork are at approximately one hundred per cent, beef at approximately 80 per cent, poultry at 85–90 per cent, and grain at 90–110 per cent depending on the harvest year. Bread grain self-sufficiency (wheat and rye) is particularly sensitive: it dropped to 68 per cent in the drought year of 2018.
The most vulnerable product groups are fruit (below 10% self-sufficiency), oilseed and protein crops (15–20%), and the aforementioned bread grain. When the import dependency of production inputs — fuel, fertiliser raw materials — is taken into account, true self-sufficiency is significantly lower than production statistics suggest.
The lesson of the 1860s
Finland's history contains one great famine, and although its mechanism was different — cold and wet, not dry — its lessons about fundamental logic are timeless.
The catastrophically rainy summer of 1865 rotted harvests in the fields. The extreme winter of 1866–1867 delayed spring by a month. Early autumn frost destroyed late-sown crops before they could mature. During 1866–1868, between 150,000 and 270,000 Finns died — approximately 8 per cent of the 1.8-million population. Only about 10 per cent of the food deficit could be covered by imports. Approximately 100,000 people took to the roads as beggars, spreading disease to previously unaffected areas. Finland's population did not return to its 1865 level until 1872 — seven years later.
No one is claiming that Finland in the 2020s is Finland in the 1860s. Healthcare, infrastructure, international trade, and preparedness are on a different level. But the fundamental logic is the same: when domestic production collapses and imports cannot compensate, stockpiles decide. And stockpiles last a finite time.
VII. Year by Year — 2026, 2027, 2028, 2029
This chapter draws together the mechanisms, yield data, and reference material from the preceding chapters into a concrete year-by-year assessment. Every figure is based on historical data or international comparison. Uncertainties are noted.
Growing season 2026: manageable on the surface, fragile underneath
Spring 2026 will likely begin close to normal: frost depth depends on late-winter snow accumulation, but even if snow falls in February and March, the groundwater deficit already exists. Under a summer drought scenario, the situation resembles 2018 but in a weaker version, because baseline soil moisture is lower.
Estimated total grain harvest: 2.5–2.8 billion kilograms — 30–35 per cent below normal. This is slightly worse than the 2018 result (2.7 billion kilograms). Rye losses of 50–70 per cent, wheat losses of 30–40 per cent. Grass forage yield drops 20–30 per cent, triggering feed procurement stress. Seed grain quality begins to deteriorate.
This is the year that still looks manageable. Reserves hold. Imports can be increased. The media reports a "poor harvest" in the same way it reported 2018. But beneath the surface lies a critical difference: soil moisture reserves do not return to normal over winter, because the winter is dry.
Growing season 2027: compound shock
The winter of 2026–2027 is the scenario's critical juncture. If it unfolds as projected — low snow, cold, SSW event probable (60–70%) — frost penetrates 80–150 centimetres in dry soil. Spring is delayed 3–6 weeks. Winter crop damage is massive. Grassland damage is widespread.
This is a compound shock: delayed sowing and a second dry summer at the same time. The effective growing season shrinks to 80–110 days in southern Finland and 60–80 days in central Finland — at or below the maturation threshold for most spring cereals.
Estimated total grain harvest: 1.5–2.0 billion kilograms — 45–60 per cent below normal. Bread grain self-sufficiency could drop to 30–50 per cent. Forage yields fall to the point where herd reduction is unavoidable: the silage deficit combined with feed grain scarcity forces farmers into slaughter decisions. Seed grain availability for 2028 becomes problematic.
The historical reference point is 1867, when a late spring and early autumn frost produced a catastrophic harvest — though the mechanism then was cold, not drought.
Growing season 2028: structural transformation
The third consecutive drought year differs qualitatively from the first two. Soil water-holding capacity has been weakened by the decline in organic matter (estimated loss of 0.3–0.5 percentage points). Soil aggregate stability has deteriorated due to repeated drying-wetting cycles. Soil microbial mass has declined and mycorrhizal networks have been disrupted. Deep soil moisture (60–150 cm) — the last reserve for stressed crops — is depleted.
Wilman et al. (1998) demonstrated that meadow fescue dies after 12–24 months of water deprivation, and that timothy, with its shallow crown-based root system, faces near-certain death after two consecutive dry growing seasons. This means that by the third year, forage grass production is no longer merely reduced — in places it has collapsed.
Estimated total grain harvest: 1.2–1.8 billion kilograms — 50–65 per cent below normal. Strategic reserves are largely spent. Significant herd reduction is underway. Farm bankruptcies are accelerating.
Growing season 2029: uncharted territory
A fourth consecutive drought year takes Finnish agriculture into territory for which there is no domestic experience. International comparisons sketch a picture of the possible:
During the intensification phase of Australia's drought (2006–2009), wheat yield was 49 per cent of normal in the first year and 61 per cent in the second, but recovered partially thanks to returning rains. Spain's drought of 2022–2024 produced 75 per cent of normal in the first year and only 47 per cent in the second, but recovered with the return of heavy rains. Syria's drought of 2007–2010, where no rain returned, held production at 45–75 per cent of normal for four years.
The Syrian comparison is the most relevant because the drought continued without interruption. It led to wheat imports for the first time in 15 years, a decline in agriculture's share of GDP from 25 to 17 per cent, and the migration of 1.5 million rural residents to cities.
Fourth-year estimate for Finland: total grain harvest approximately 1.0–1.5 billion kilograms — 55–70 per cent below normal. The dairy herd has been significantly reduced and recovery is not possible for years. The rate of farm closures has accelerated. Soil structure has deteriorated in ways that take years to repair even after the drought ends.
Timeline as a table
Below is a summary of key indicators by year. The figures are estimates based on historical data and international comparisons. Actual outcomes depend on realised weather conditions.
Growing season 2026: grain harvest estimated at 2.5–2.8 bn kg (normal 3.4–3.5), shortfall from normal 25–35%, dairy herd near normal, reserves sufficient.
Growing season 2027: grain harvest estimated at 1.5–2.0 bn kg, shortfall 45–60%, dairy herd reduction begins, reserves drawn down significantly.
Growing season 2028: grain harvest estimated at 1.2–1.8 bn kg, shortfall 50–65%, dairy herd reduced by an estimated 15–25%, reserves largely spent.
Growing season 2029: grain harvest estimated at 1.0–1.5 bn kg, shortfall 55–70%, dairy herd reduced by an estimated 25–35%, reserves depleted or nearly depleted.
VIII. What This Means
The purpose of this article is not to provoke panic. Panic helps no one. Its purpose is to state what the data says, as clearly as we can, so that everyone can draw their own conclusions.
What is known
Finland's groundwater is currently 40–90 centimetres below normal. January 2026 was the driest in recorded history. The polar vortex has been disrupted in a pattern that favours the recurrence of dry, cold winters. The probability of an SSW event next winter is high. Soil moisture conditions are weaker than at the beginning of any previous reference year.
What this means in practice
Perhaps the most important conclusion of this analysis is this: by the time multi-year drought becomes visible — at the earliest, by the end of the second drought year — the most significant damage pathways are already well advanced. Herd reduction has begun and cannot be reversed. Farms have closed and will not reopen. The soil has deteriorated and will not recover with a single season of rain.
This means that the time to prepare is not when the crisis becomes visible. It is now.
Everyone can assess their own situation: how dependent am I on a functioning supply chain, how long will my food and water last, and what can I do to reduce my vulnerability? This article does not give ready-made answers to these questions — they depend on each person's own circumstances — but it provides the basis for asking them.
Finland is exceptionally well prepared for isolated crises. The National Emergency Supply Agency's reserves, the comprehensive security model, and a robust societal structure are genuine strengths — but they are designed for short-duration disruptions, not a multi-year production collapse. The distinction is decisive.
The data is public. It does not lie. Every figure cited in this article is verifiable from primary sources. What each person does with this information is each person's own decision.
