Shifting Seasons

Warm / cold seasonsKöppen Dfc · Continental

How spring and autumn have shifted in Finland. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (1.7°C, from 19401969); autumn is the date they fall back below it. Temperature swings 26.4°C peak-to-peak across the year - a classic four-seasons rhythm.

Data Sources

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 headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.

What is the climate like in Finland?

Finland has a continental climate (Köppen Dfc: Subarctic), with distinct warm summers and cool-to-cold winters. July is typically the warmest month, averaging 16.6°C, while January is the coldest at -8.2°C. Annual precipitation averages around 607mm, spread fairly evenly across the year.

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.

What counts as a Heatwave Day on the Finland climate page?

Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.

Does the Finland climate page include frost and snow data?

Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
