Why is there a heatwave in Europe?
Since late May 2026, Europe has experienced several severe heatwaves, with intense heat affecting different regions.
Persistent high-pressure systems have created heat domes that trap hot air from North Africa, resulting in clear skies, limited rainfall, and prolonged extreme temperatures.
Climate change is contributing to the increasing intensity and frequency of extreme heat in Europe, which is warming faster than any other continent (1).
Which countries are affected by the heatwave?
The current heatwave is primarily affecting Southern Europe (2). Countries currently experiencing extreme heat include:
- Albania
- Bosnia and Herzegovina
- Croatia
- France
- Greece
- Italy
- Montenegro
- North Macedonia
- Portugal
- Spain
- Turkey
Additional areas may be affected as further heatwave phases develop.
How long will the heatwave last?
Temperatures in the hottest areas are exceeding 40°C (104°F). Heatwave conditions are expected to continue in parts of Europe through August, with successive heat phases affecting different regions (3).
Prolonged heat is worsening drought conditions and increasing wildfire risk across affected areas.
Are there any alerts in place?
National meteorological agencies continue to issue heat warnings as conditions develop, with alert levels varying by country and region (4).
Authorities recommend limiting outdoor activity during peak heat, staying hydrated, seeking air-conditioned or cool environments, and checking on vulnerable people.
Residents should follow local weather services and health authorities for the latest heat warnings and safety guidance.
