Finland Climate
Top 5 Cities: Helsinki, Espoo, Tampere, Vantaa, and Oulu
This month in numbers
Finland experienced its 6th warmest February–April on record, with an average temperature of -1.41°C, a significant 3.9°C above the 1961–1990 baseline. April 2026 itself was the 23rd warmest April on record, with an anomaly of +1.8°C. Globally, April 2026 was the 2nd warmest April for land temperatures, at 14.96°C, an anomaly of +1.1°C. The February–April period also ranked as the 2nd warmest globally for land temperatures.
What changed
This three-month period continues a trend of warmer-than-average conditions for Finland. The country's 3-month anomaly of +3.9°C places it 18th warmest out of 234 regions in cross-region rankings, highlighting a significant regional warming trend. Finland's long-term warming trend is +1.84°C compared to the 1961–1990 baseline, and 2025 was the 3rd warmest year on record. Finland is part of a broader European warming trend, with 8 of the top 10 warmest 12-month rolling anomalies being European countries.
What’s driving change?
The significant warming observed in Finland is largely driven by , where the Arctic region warms at a faster rate than the global average. This is further influenced by , with winters in Finland becoming progressively milder and shorter, and spring arriving earlier. The Finnish Meteorological Institute has noted 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 a strong forecast for El Niño developing in the coming months, its direct influence on Finland's recent warming is likely muted. However, a strengthening high-pressure system over central Europe in March brought warm, dry airflows to Finland, contributing to the mild conditions.
Looking ahead
Projections suggest that warming in Central Finland will continue, with temperatures expected to rise by at least two degrees Celsius by the end of the century, leading to progressively milder and wetter winters, and potentially more frequent late-summer droughts.

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?

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.
