Sweden Climate – June 2026 Update
Top 5 Cities: Stockholm, Gothenburg, Malmö, Uppsala, and Västerås
This month in numbers
Sweden experienced a slightly cooler June, with an average temperature of 12.3°C, which is 0.3°C below the 1961–1990 baseline and ranked as the 42nd warmest June in 86 years of records. Globally, June 2026 was the 3rd warmest June on record for land temperatures, with an anomaly of +1°C above the 1961–1990 average. The three-month period from April to June 2026 saw Sweden's average temperature reach 8.06°C, an increase of 1.1°C above the baseline, making it the 19th warmest such period on record.
What changed
While June itself was slightly cooler than average for Sweden, the broader seasonal trend for April to June indicates a significantly warmer period, ranking among the top 20 warmest on record. This contrasts with the global picture, where land temperatures for the same three-month period ranked as the 2nd warmest on record. Sweden's June anomaly of -0.3°C placed it 220th out of 234 regions globally for the latest month's temperature anomaly, indicating that many other regions experienced considerably warmer conditions. Western Europe, for instance, recorded its hottest June on record.
What’s driving change?
The ongoing weak El Niño, with a current anomaly of +0.98°C, is a significant global climate driver. While El Niño typically brings cooler late winters to Scandinavia, its direct impact on Sweden's summer temperatures is less clear. However, a strong El Niño is forecast to persist through the end of the year and into spring 2027, with an 81% chance of developing into a very strong event that could rank among the largest on record. This could amplify extreme weather events globally. In June, southern Sweden experienced a heatwave with temperatures exceeding 30°C, prompting orange and yellow warnings from the Swedish Meteorological and Hydrological Institute (SMHI). This heat was linked to a broader heatwave affecting central and southern Europe. Towards the end of June, Scandinavia also saw violent thunderstorms and large hail.

Shifting Seasons
Warm / cold seasonsKöppen Dfc · ContinentalHow spring and autumn have shifted in Sweden. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (2.5°C, from 1940–1969); autumn is the date they fall back below it. Temperature swings 23.3°C peak-to-peak across the year - a classic four-seasons rhythm.

FAQs
FAQs
How is the climate in Sweden changing?
Sweden 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 Sweden come from?
Climate data for Sweden 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 Sweden climate data cover?

How often is the Sweden climate update refreshed?
The Sweden 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.
