Finland Climate
Top 5 Cities: Helsinki, Espoo, Tampere, Vantaa, and Oulu
This month in numbers
Finland experienced an April that was 1.8°C warmer than the 1961–1990 baseline, with an average temperature of 2.11°C, ranking it the 23rd warmest April in 86 years of records. Globally, April 2026 was the 2nd warmest April on record for land temperatures, with an anomaly of +1.1°C. The three-month period from February to April 2026 saw an average temperature of -1.41°C, a significant 3.9°C above the baseline, making it the 6th warmest such period on record for Finland.
What changed
This past three-month period (February–April 2026) in Finland was notably warm, ranking as the 6th warmest on record. This trend aligns with Finland's long-term warming, which has seen an increase of +1.84°C compared to the 1961–1990 baseline. Finland's 3-month anomaly of +3.91°C places it 19th globally in cross-region rankings, indicating a significant warming compared to many other areas. For the latest month, Finland's anomaly was 0.64°C cooler than the overall European group average, suggesting that while still warm, the warming was less pronounced than in some other parts of the continent.
What’s driving change?
The significant warming observed in Finland, particularly during winter months, is largely driven by , where high northern latitudes are warming at an accelerated rate. This is further influenced by , with winters becoming milder and shorter, and spring arriving earlier. The Finnish Meteorological Institute has reported that Finland's climate has warmed faster than the global average in recent decades, with the rate of warming more than doubling over the past 25 years. While the current ENSO state is Neutral, with an anomaly of +0.11°C for February-April 2026, a shift towards El Niño is forecast, with a 61% probability for May-July and 79% for June-August. In December 2025, winter storm Hannes brought strong winds, heavy snow, and widespread power cuts across Finland, with gusts exceeding 30 metres per second in coastal areas. This was followed by a deep freeze in January 2026, which saw temperatures drop to nearly -40°C in northern Lapland, leading to flight cancellations and stranded tourists.
Looking ahead
With an evolving El Niño phase strongly forecast for the coming months, Finland may experience cooler late winters in the future, although very strong El Niños have historically led to warmer winters.

Data Sources for Finland
Every figure on this page is sourced from official, openly published climate datasets. Anomalies are calculated against the 1961–1990 baseline (temperature) and 1991–2020 (rainfall, sunshine, frost) — see the Methodology & Sources page for the complete dataset list and update calendar.
FAQs
FAQs
How is the climate in Finland changing?
Finland is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The trend rate is shown as °C per decade in the headline panel; you can also see the warmest and coolest years on file.
Where does the climate data for Finland come from?
Climate data for Finland comes from Our World in Data, sourcing Copernicus ERA5 and HadCRUT5 (national temperature anomaly) and the Global Carbon Project via Our World in Data (CO₂ emissions), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the Finland climate data cover?
The Finland climate profile covers Helsinki, Espoo, Tampere, Vantaa and surrounding areas. Temperature, rainfall and emissions data for Finland
How often is the Finland climate update refreshed?
The Finland climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
