> France issued its highest heat emergency across 35 departments as a heat dome threatens to shatter all-time temperature records on the summer solstice.

France declared its highest-level heat emergency — red alert — across 35 departments on Sunday, June 21, the summer solstice, as a relentless heat dome pushed temperatures toward potentially record-breaking levels. Météo-France warned that Monday, June 22, could become "the hottest day ever recorded in France," with highs of 37°C to 42°C and overnight lows remaining dangerously above 22°C.

The crisis disrupted Fête de la Musique, France's beloved annual midsummer music celebration, with dozens of cities — including Nanterre and Brive-la-Gaillarde — cancelling events. Authorities banned alcohol consumption at outdoor gatherings across 35 departments. State rail operator SNCF cancelled 71 train services and schools in Paris and Toulouse closed their doors. The government activated its Heatwave Information Hotline (0800 06 66 66), and at least one heat-related death has already been reported.

In total, 61 French departments are under some level of heat alert, with 51 imposing water restrictions. Meteorologists warn the heatwave may persist through late June, creating a prolonged period of danger for the entire population — not only vulnerable groups.
