PARIS – A record-shattering heat wave that swept across Western Europe last June left a far deadlier mark on France than initial projections indicated, according to updated data from the nation’s public health watchdog. Released Friday, the latest figures from Public Health France show excess deaths jumped by nearly a third during the week of the most extreme heat, with more than 2,000 additional fatalities recorded compared to the preceding week when temperatures first began their dangerous climb. The new tally is double the agency’s initial preliminary estimate of 1,000 extra deaths published just one week earlier, which only covered the three hottest days of the weather event.
The extreme heat event, which gripped much of Western Europe in mid-to-late June, pushed temperatures past all-time records for both daytime highs and overnight lows across dozens of French cities and towns between June 22 and June 28. The unrelenting heat overwhelmed emergency healthcare services across the country, as thousands of patients sought treatment for heat-related complications.
At Paris-Saclay Hospital, emergency department director Dr. Nicolas Gonzales told the Associated Press that a flood of heat-exposed patients began pouring into the facility starting June 20. Medical teams treated patients across all age groups, from young children to isolated elderly residents, for life-threatening heat-linked conditions including heart attacks, acute dehydration, and sudden kidney dysfunction.
The strain extended far beyond hospital wards, as funeral and mortuary services in the capital struggled to keep up with the sudden rise in fatalities. Paris funeral directors report widespread logjams, with some local mortuaries hitting full capacity and forced to turn away new bodies ahead of burials or cremations.
Public Health France’s current count stands at 8,973 total deaths recorded for the week of June 22 to 28, a 29% increase from the 6,948 deaths registered the prior week, when the heat wave first began building. The 2,025 gap between the two weekly totals counts excess deaths across all age groups and all causes, most of which are attributed directly or indirectly to the extreme heat.
Disaggregated data shows the most dramatic spike in fatalities occurred in private residences, where deaths rose a staggering 91% week-over-week. Fatalities in elderly care facilities jumped 37%, while hospital deaths increased by nearly 20%. The Paris region bore the brunt of the mortality surge, recording a 63% week-on-week increase in deaths.
Public health officials have cautioned that the current figures remain incomplete, meaning the final death toll will likely be even higher than the current reported numbers. “The mortality will as a consequence be higher than these first figures,” the agency stated. The record heat event that impacted France also broke temperature benchmarks across multiple other European nations, amplifying concerns about the growing public health risks of extreme weather linked to climate change.
