Key Points

• From June 28 to 30, 2025, amid a heat wave, Météo-France issued an orange alert for Haute-Corse (covering 52.5% of the region’s resident population) and a yellow alert for Corse-du-Sud (47.5% of the region’s resident population) for July 1, 2025. The heatwave is still ongoing.

• A regional analysis of emergency care utilization indicates that the iCanicule composite health indicator (covering hyperthermia, dehydration, and hyponatremia) has remained stable since the start of the heatwave. SOS Médecins call volumes were very low.
