This month in numbers

Slovenia experienced its 8th warmest April on record in 2026, with an average temperature of 11.34°C, a significant 2.6°C above the 1961–1990 baseline. Globally, April 2026 was the 2nd warmest April for land temperatures on record, with an anomaly of +1.1°C.

What changed

The period from February to April 2026 was the 13th warmest such period on record for Slovenia, with an average temperature of 6.68°C, which is 2.3°C above the long-term average. This warming trend in Slovenia aligns with a broader global pattern, as global land temperatures for the same three-month period ranked as the 2nd warmest on record. Looking at the cross-region rankings, Slovenia's 12-month rolling anomaly places it 39th warmest out of 234 regions, indicating a sustained period of elevated temperatures.

What’s driving change?

Slovenia's warming trend is influenced by broader climate patterns, including the , where higher-latitude regions tend to warm faster than tropical areas. The country has also been significantly impacted by extreme weather events in recent years. In August 2023, Slovenia experienced its worst natural disaster since independence, with major floods and landslides affecting two-thirds of the country due to heavy rainfall. This event caused an estimated €9.9 billion in economic losses and resulted in seven fatalities. Further heavy rains in late October and early November 2023 also led to significant flooding in the Tolmin region. These events highlight the increasing vulnerability of Slovenia to climate change impacts. More information on extreme weather can be found at Extreme Weather tracker.

Looking ahead

Slovenia is actively pursuing ambitious green transition goals, aiming for climate neutrality by 2045, five years ahead of the EU's general framework.

FAQs

FAQs

How is the climate in Slovenia changing?

Slovenia 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 Slovenia come from?

Climate data for Slovenia 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 Slovenia climate data cover?

How often is the Slovenia climate update refreshed?

The Slovenia 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.
