Nearly 30% additional deaths were recorded between June 22 and 28, 2026 compared to the previous week, according to initial data from Public Health France. These figures, still provisional, come after an episode of heatwave whose health impact will be assessed in the coming weeks.
A marked increase in deaths, but data still provisional
The first indicators from Public Health France show a 29.1% increase in deaths from all causes during the week of June 22 to 28, 2026, compared to the previous week.
Concretely, 8,973 deaths were recorded over this period, compared to 6,948 between June 15 and 21, or 2,025 additional deaths.
These figures are based on electronic death certificates and remain unconsolidated. They include data available until June 28, but do not yet cover all deaths that have occurred. Public Health France therefore insists on the need to interpret them with caution.
The increase mainly concerns people aged 45 and over (+29.7%, or 2,001 additional deaths).
Deaths on the rise especially at home and in several regions
The increase is observed in all places of death, but it appears particularly significant at home, with an increase of 91% (data still to be consolidated).
Other places are also affected:
- EHPAD: +37%;
- Health establishments: +19.7%.
Geographically, the increase is noted in almost all metropolitan regions, with the exception of Occitanie and Auvergne-Rhône-Alpes.
The largest increases are noted in:
- Île-de-France: +62.8% (+619 deaths);
- Pays de la Loire: +62.0% (+178 deaths);
- Normandy: +53.1% (+216 deaths);
- Centre-Val de Loire: +47.3% (+121 deaths);
- Brittany: +36.0% (+129 deaths);
- New Aquitaine: +28.1% (+264 deaths);
- Hauts-de-France: +27.7% (+155 deaths).
A link with the heatwave? We will have to wait for the consolidated analyzes
These data are published as part of the weekly monitoring of all-cause mortality carried out by Public Health France. At this stage, they do not make it possible to precisely measure the impact of the June heatwave.
The organization specifies that a specific bulletin dedicated to excess mortality during this episode will be published three weeks after the end of the heat wave, time to consolidate around 95% of deaths using data from civil status offices.
This estimate will be based on a comparison between the mortality observed during the heatwave and mortality expected during normal periods.
At the same time, Public Health France is also developing a method to estimate deaths attributable to heat, at the departmental level, in order to better measure the weight of exposure to high temperatures on annual mortality.
Why these first figures should be interpreted with caution
The surveillance presented is mainly based on electronic death certificates, which allow very rapid monitoring of the situation but usually only cover around 60% of national mortality.
Coverage varies depending on the place of death: around 25% of deaths at home, 45% in EHPADs and almost 80% in hospitals are recorded via this system.
In other words, these initial data are underestimated, particularly for deaths occurring at home. The final figures will therefore probably be higher once all the data is consolidated.
