Key Points 

• According to Météo France, the Occitanie region experienced a heat wave from
  June 19 to 28, 2026 (departments were placed under orange or red heat wave alerts).
• A regional analysis of emergency care utilization shows an increase in the composite health indicator iCanicule (which includes cases of hyperthermia, dehydration, and hyponatremia) during this heat wave across all data
  sources (SOS Médecins calls, emergency
  department visits, and hospitalizations following emergency department visits).
• This trend affected all age groups, and the majority of the
  region’s departments were affected, including those under a yellow heatwave
  alert (Mediterranean coastline).
• Subject to the completeness of the data available as of June 30, these surveillance indicators have now shown a decrease compared to previous days.
