France's public health authority reported a provisional total of 7,919 excess deaths linked to extreme heat from late May to August 20 during the country's hottest summer since 1900. The deadliest period was June 17–July 2, and older people were hit particularly hard, with a notable spike in mid-August. Officials expect to finish data collection by the end of October and will publish a final tally early next year.

France's hottest summer since 1900 — marked by a succession of intense heatwaves — has been linked to a provisional total of 7,919 excess deaths from late May through August 20, the country's public health authority reported on Wednesday.
The figure is provisional and could rise as data from the final weeks of the season are processed, officials said. By comparison, France recorded 5,722 excess heat-related deaths between June and mid-September last year.
Key figures and timeline
The public health authority provided a breakdown of the provisional toll:
- 5,764 excess deaths during the first major episode: June 17–July 2 (the deadliest spell)
- 1,243 excess deaths from July 3–20
- 817 excess deaths from July 27–August 20
- 95 excess deaths during an early spike: May 24–28
"This summer of 2026 was completely unprecedented, with almost continuous heatwave episodes," Guillaume Boulanger, head of the Living and Working Environments unit at France's public health authority, told AFP.
Officials noted a sharp, early spike in fatalities after the very hottest days, particularly a surge in deaths recorded on August 14–16. Older people were disproportionately affected this year.
Context and contributing factors
France still recalls the catastrophic 2003 heatwave — estimated to have caused about 15,000 deaths — which struck during peak holiday season when medical services were strained and many older people were isolated. Weather authorities say the 2026 summer surpassed both the 2003 and 2022 heat events to become the hottest since 1900.
Climate scientists and public-health experts attribute the increasing frequency and severity of heatwaves largely to climate change driven by the burning of coal, oil and gas. The public health authority said the death toll highlights vulnerabilities in buildings, workplaces and infrastructure that are not well adapted to extreme heat.
The authority expects to complete data collection by the end of October, with a final consolidated tally for the summer due to be announced early next year.
What this means: The provisional numbers underscore the growing human cost of more frequent, intense heatwaves and the importance of targeted protection for older adults, improved heat-preparedness in health and social care, and long-term climate mitigation and adaptation measures.
