France's third summer heatwave is forecast to intensify and spread

What happened

Le Monde reports that Météo-France expects the heatwave that began July 28 to persist and spread north and east, with temperatures again reaching roughly 35 to 40 degrees Celsius in several regions from August 10. The national thermal index is forecast to remain above France's heatwave threshold, potentially making this one of the country's longest observed heatwaves.

Why it matters

Long heat episodes compound health, water, agriculture, power, and workplace risks because nights and buildings have less time to cool. Forecasts can guide immediate precautions, but the summer's repeated events also strengthen the case for heat-resilient housing, public cooling, urban shade, and health systems.

What to watch

• Updated Météo-France alerts, nighttime temperatures, and the duration of threshold exceedance.
• Public-health impacts and protection for older adults, workers, and people without adequate cooling.
• River levels, agriculture, wildfire conditions, and heat-related limits on power generation.
