Finland Climate – June 2026 Update
Top 5 Cities: Helsinki, Espoo, Tampere, Vantaa, and Oulu
This month in numbers
Finland experienced a cooler-than-average June, with the mean temperature of 12.35°C ranking as the 54th coolest June in 86 years of records, an anomaly of -0.9°C compared to the 1961–1990 baseline. This stands in contrast to the global picture, where June 2026 was the 3rd warmest June on record for global land temperatures, with an anomaly of +1°C. The three-month period from April to June 2026 was slightly warmer than average in Finland, ranking as the 38th warmest on record with an anomaly of +0.3°C.
What changed
While Finland saw a cooler June, the broader European context reveals a significant heatwave across Western and Central Europe during the same month. Western Europe recorded its hottest June on record, with temperatures more than 3°C above the 1991-2020 average. Finland's June anomaly of -0.9°C placed it as the 3rd coolest country globally for the month, highlighting a regional divergence from the widespread European warmth. Over the past 12 months, Finland has experienced a rolling anomaly of +2.74°C, ranking it as the 18th warmest globally.
What’s driving change?
The current climate pattern is influenced by a strong El Niño, which is expected to persist through the end of the year. The NOAA ONI 3-month average for April-June 2026 shows a weak El Niño with an anomaly of +0.98°C, and forecasts indicate a 100% probability of El Niño continuing through October-December 2026. While El Niño typically brings cooler late winters to Northern Europe, its impact on Finnish summer conditions is less consistent. The widespread heatwave across much of Europe in June was attributed to a powerful heat dome, trapping hot air and preventing cooler Atlantic systems from offering relief.
Looking ahead
The ongoing strong El Niño is expected to continue, and while its direct impact on Finland's summer is uncertain, studies suggest a tendency for cooler late winters in Northern Europe during El Niño years.

Shifting Seasons
Warm / cold seasonsKöppen Dfc · ContinentalHow 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 1940–1969); 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.

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.
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.
