France recorded 5,764 excess deaths during a historic heat wave that spanned from June 17 to July 2, according to the public health agency, Apnews reports. This figure reflects a 36% increase in mortality compared to what would typically be expected for that period, marking the highest excess death toll from a heat wave in the country since 2003, when an estimated 15,000 people died.
The Scope of the Crisis
Public Health France reached its total by comparing the 21,674 deaths recorded from all causes in heat-affected regions against a baseline of 15,910 expected deaths, derived from statistical modeling of previous years. The agency noted that this latest estimate is significantly higher than initial reports, which had previously suggested approximately 2,000 additional deaths during the peak week of June 22 to June 28. Officials caution that this number remains an estimate and will be updated later in the year as more complete data becomes available.
The Paris region suffered the most significant impact, recording 1,999 unexpected deaths—a figure approximately 80% higher than would have been anticipated under normal conditions, CBS News reports.
Intensity and Timing
The heat wave was characterized by its early onset and duration, exposing the population to extreme temperatures while schools and workplaces were still active. France registered its hottest-ever days on June 24 and June 25, with a national average of 30 C (86 F) and peak temperatures soaring well above 40 C (104 F) in many locations.
According to The Guardian, just over half of the excess deaths occurred during a three-day window from June 25 to June 27. Furthermore, individuals aged 75 and older accounted for approximately two-thirds of the total excess mortality reported by the agency.

Systemic Strain and Challenges
The surge in mortality placed immense pressure on medical and funeral infrastructure. Nearly half of the 21,674 people who died passed away in hospitals, which reported a heavy influx of patients suffering from heat-related ailments. About one-third of the deaths occurred at home, while the remainder largely occurred in care homes for older people.
In Paris, funeral directors reported significant difficulties in managing the volume of the deceased. Some mortuaries reached full capacity and were forced to turn bodies away, complicating the process of arranging burials or cremations. Additionally, authorities noted that throughout June, 40 drowning deaths were recorded in a single week as residents sought relief from the heat in bodies of water.
Broader Context and Limitations
Experts emphasize that the true impact of extreme heat is difficult to quantify because many heat-related deaths are not formally documented as such. For instance, a death certificate might list a heart attack as the cause of death, even if that event was triggered by heat exposure in an elderly person or someone with underlying health issues.
Across Europe, the heat wave was part of a larger trend of extreme temperatures that arrived exceptionally early in the season. Figures emerging from across the continent suggest that well over 10,000 more deaths occurred at the height of the heat wave than would normally be expected. Throughout Western Europe, the Copernicus Climate Change Service reported that it was the hottest June on record. As noted by newsday.com, the French health agency continues to analyze the data to provide a more comprehensive picture of the event’s human toll.
