PARIS — Record-breaking summer heatwaves pushed temperatures above 40 degrees Celsius in areas inhabited by 80 million people across Europe between mid-June and mid-August 2026, according to official data analyzed and published on Thursday, August 21, 2026.
The intense thermal conditions, fueled by climate change, triggered severe droughts, sparked wildfires, reduced agricultural crop yields, and contributed to more than 25,000 excess deaths across the continent. According to the European Union's Copernicus Climate Change Service, Western Europe recorded its hottest start to summer in 2026, with June and July temperatures reaching unprecedented levels.
Geographic Distribution and Mortality Figures
The analysis, based on temperature metrics from the European Drought Observatory and population data from the EU's Joint Research Centre, revealed stark national distributions. Since mid-June, 30 million people in France, 23 million in Spain, and eight million each in Germany and Italy experienced temperatures above 40 degrees Celsius at least once. Many affected regions lacked widespread cooling infrastructure, leaving vulnerable populations exposed.
Official mortality tracking showed a record 14,000 heat-related deaths in Germany this summer, alongside 7,300 in France and 4,500 in Spain. Furthermore, temperatures exceeded 35 degrees Celsius in regions inhabited by about 490 million people, representing roughly 80 percent of Europe's total population.
Broader Climate Impacts
In France, more than 20 million residents endured temperatures above 35 degrees Celsius for at least 21 consecutive days, marking a fivefold increase compared to the summer of 2022. Historically cooler nations such as Britain, Belgium, the Netherlands, and Poland also recorded extreme heat spikes.
Public health authorities across the affected member states continue to evaluate preliminary mortality figures as local agencies compile final epidemiological reports.
How many people in Europe experienced temperatures above 40C during the summer heatwaves?
Extreme summer heatwaves exposed 80 million people to temperatures exceeding 40 degrees Celsius across Europe between mid-June and mid-August 2026, according to official data analyzed from the European Drought Observatory and the EU Joint Research Centre.
The comprehensive findings were released publicly on August 21, 2026.
Public health agencies are scheduled to finalize full mortality assessments at the conclusion of the meteorological season.
