Key Points

• On June 22, 2026, the Orne department was placed under a red heat wave alert, joined by the four other
  departments in Normandy from June 23, 2026, through June 25, 2026, for the Manche department, and
  through June 26, 2026, for the other departments.
• A regional analysis of emergency care utilization indicates a significant increase
  in the composite health indicator iCanicule (which includes hyperthermia,
  dehydration, and hyponatremia) coinciding with rising temperatures.
• The levels reached by this indicator are higher than those observed during the heat wave at the end of May 2026 and are unprecedented in Normandy since monitoring
  began.
• The trends in the monitored indicators are consistent across departments, with an increase in the indicators observable in all departments.
