French public health authorities have reported that at least 5,700 more people died than typically expected during a historic heat wave that swept across the country last month. This figure marks a significant increase in the nationwide death toll following the record-breaking temperatures experienced throughout June and into early July.
According to Public Health France, regions affected by the extreme heat between June 17 and July 2 recorded 21,674 deaths from all causes. Statistical modeling based on data from previous years suggests that without the heat wave, those same regions would have expected 15,910 deaths. The difference of 5,764 is categorized as "excess" mortality, representing a 36% increase over normal expectations. This is the highest mortality figure attributed to a heat wave in the country since 2003, when an estimated 15,000 people died during a similar historic event.
France experienced its hottest days on record on June 24 and June 25, with national average temperatures reaching 86 degrees Fahrenheit. Many locations saw peak temperatures exceeding 104 degrees, coupled with record-breaking nighttime heat. The agency noted that over half of these unexpected deaths occurred during the three-day period from June 25 to June 27, which marked the peak of the heat wave.
"This unprecedented episode, characterized by its early onset, intensity, and duration, exposed nearly the entire population to extreme heat during a period when school and work activities were still in full swing," the public health agency stated. Additionally, the extreme conditions led to 40 drowning deaths over a single week in June as residents sought relief in water.
The Paris region was particularly hard hit, recording 1,999 unexpected deaths, which is approximately 80% higher than normal anticipated levels. Funeral directors in the capital reported significant challenges in storing bodies, with some mortuaries reaching capacity and being forced to turn families away. Across Europe, the Copernicus Climate Change Service confirmed it was the hottest June on record. Climate expert Samantha Burgess noted that the findings underscore profound changes in the climate system as it continues to accumulate heat. Across the continent, reports suggest well over 10,000 excess deaths occurred during the height of the heat wave.
