PARIS, France (AFP) — Europe’s deadly heatwave pushed east Sunday with hundreds of millions still sweltering across the continent despite fleeting relief from overnight storms, notably in France and Belgium.

The heat remained intense across central and eastern Europe, with the Czech Republic, Hungary and Poland hit hard as temperatures soared and records fell. At least 191 million Europeans were expected to face temperatures above 35C during the day, according to Agence France-Presse estimates.

The World Health Organization (WHO) said it had recorded more than 1,300 excess deaths in Europe since 21 June. Overall, some 381 million Europeans were set to see temperatures exceed 30C, according to analysis based on forecasts from the German Meteorological Service and population data.

This heatwave is the most severe ever recorded in Europe, and would have been “virtually impossible” this early in the summer without climate change, the World Weather Attribution group of scientists said.

All-time temperature records have been broken in Germany, Poland and the Czech Republic, as well as for the month of June in the UK and in Switzerland.

‘Not a fiasco’

“Right now 150 million people are living under extreme heat, hundreds have died, schools are shut, grids are buckling,” WHO chief Tedros Adhanom Ghebreyesus said on X.

“Europe is the fastest-warming continent on Earth, heating at twice the global average,” he warned.

Storms brought some respite overnight, particularly in France after several days of temperatures close to 40C. But they also caused damage, as a man died near Brussels when a tree fell on his car, local media reported.

In France, the highest-level heat alerts were expected to ease on Sunday evening, although millions continued to endure sweltering conditions.

Still marked by the 2003 heatwave — Europe’s worst in centuries, which killed around 15,000 people — French authorities feared a rising death toll.

The country’s national health agency said Sunday it had tallied around 1,000 more deaths than expected from 24 June, and warned the figure was likely to increase further.

Many of those fatalities are among those aged 65 and over, it said.

Interior Minister Laurent Nunez rejected criticism from opposition deputies over the response, insisting: “This is not a fiasco -- we were prepared.”

Prime Minister Sebastien Lecornu has called a special cabinet meeting to discuss how to learn the lessons from the recent heatwaves and to prepare for the possibility of more, his office announced.

French weather agency France-Meteo said on Sunday evening it was already anticipating the possibility of another heatwave in July.
