• From August 8 to 11, 2025, amid a heat wave, Météo-France classified 6 departments as under red alert (covering 46.8% of the region’s resident population) and 7 departments as under orange alert (covering 53.2% of the region’s resident population).

• A regional analysis of emergency care utilization indicates an increase in the iCanicule composite health indicator (covering hyperthermia, dehydration, and hyponatremia) over the past three days.This trend falls within the expected fluctuations during periods of intense summer heat and is particularly evident in the departments of Haute-Garonne (red heatwave alert), Gers (red heatwave alert), Hautes-Pyrénées (orange heatwave alert), and Pyrénées-Orientales (orange heatwave alert).

• Heat poses a health risk to the entire population. The observed health impacts underscore the importance of implementing preventive measures to mitigate the effects of the heat.
