Key Points

• According to Météo France, the heat wave is expected to last from June 29 to July 3 in Bourgogne-Franche-Comté. Tuesday and Wednesday will be the hottest days of the heat wave. Nighttime temperatures will remain very high through the night of Wednesday into Thursday. The heatwave could last until Thursday morning in western Bourgogne-Franche-Comté and until Friday morning further east.

• A regional analysis of emergency care utilization indicates that the iCanicule composite health indicator (covering heatstroke, dehydration, and hyponatremia) remained stable on the first day of the heatwave (Sunday, June 29). This trend falls within the expected fluctuations for the current weather conditions and is observable across the region as a whole.

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