More than 5,000 people died due to heat in France during the summer of 2023. One in ten deaths are linked to extreme heat, according to Public Health France.

Of the 5000 dead, 3700 were over 75 years old. This summer remains, despite long periods of gloomy weather, the fourth hottest ever observed in France - the first measurements dating back to 1900. The heatwaves were particularly notable for the late nature of two of them: the longest in August, then a last one in September.
