Key Points

• According to Météo-France, the Occitanie region has been experiencing a heat wave that has been ongoing since July 4, 2026. Météo-France issued an orange alert for July 7, 2026, covering 12 departments (Ariège, Aude, Aveyron, Gard, Haute-Garonne, Gers, Hérault, Lot, Hautes-Pyrénées, Pyrénées-Orientales, Tarn, and Tarn-et-Garonne—representing 98.7% of the region’s resident population)—and a yellow alert for 1 department (Lozère, representing 1.3% of the region’s resident population).
• A regional analysis of emergency care utilization indicates a slight increase in the iCanicule composite health indicator (which includes hyperthermia, dehydration, and hyponatremia) since the start of the heat wave. This trend falls within the expected range of fluctuations given the current weather conditions.
  An analysis of SOS Médecins calls across the entire region shows an increase in iCanicule indicators (18 calls on July 6 versus 5 calls on July 5, with the increase in call volume primarily among those aged 15–74).
• 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.
