France recorded 5,764 more deaths than usual during a record-breaking heatwave last month, health authorities said on Wednesday, describing the excess mortality among people aged 15 and older as “unprecedented”.

n

It was the highest excess mortality rate during a heatwave in the country since a devastating episode of high temperatures in 2003 that killed around 15,000 people, they added.

n

Three heatwaves have swept across France since May, the latest in increasingly frequent such extreme weather events that scientists have linked to man-made climate change.

n

The soaring temperatures caused havoc in a country where many homes, schools and hospitals are not designed for heat and do not have air conditioning.

n

They have also dried up riverbeds and sparked wildfires, including one that last week ravaged a tenth of the vast UNESCO-listed forest of Fontainebleau outside Paris.

n

The extra deaths between June 17 and July 2 this year were due to “all causes” — none yet clearly linked to the heat, Sante Public France said, saying final figures would be published in the autumn.

n

In comparison, the country reported 5,722 excess fatalities linked to high temperatures between June and mid-September last year.

n

Of the excess deaths last month, around two-thirds were people aged 75 or older, while less than a fifth were aged 45 to 64.

n

Half passed away in just three days from June 25 to 27.

– Paris deaths spike –

n

France last month recorded its hottest June since records began in 1947 with a heatwave that saw temperatures spike above 40C in many places.

n

The average temperatures on June 24 and 25, 2026, were the highest ever recorded in France, all months combined.

n

Deaths in the Paris region rose by 80 percent, Sante Public France said, after saying last week they doubled in the week of June 22 to 28.

n

During that last week of June, four young children died across France after finding themselves trapped in boiling hot cars.

n

This did not however appear to affect official death rates for that age category.

n

At least 300 more people died than usual during an uncommonly early first heatwave in May.

n

Scientists have said human-caused climate change was “unequivocally” responsible for the intensity of the heatwave that battered Europe in late June.

n

Of the 53 heatwaves recorded nationwide since 1947 until late June, half have occurred since 2010, according to national met office Meteo-France.
