France has issued a red alert as an intense heatwave sweeps across the country, with temperatures soaring to 43 degrees Celsius (109.4 degrees Fahrenheit) in Rennes on Monday, June 22, 2026. The extreme heat is forecast to potentially break all-time national records, according to the Associated Press.
Historic Temperatures Recorded
A drugstore sign in Rennes, western France, displayed the scorching temperature of 43°C, captured in an AP photo by Jeremias Gonzalez. This reading is among the highest ever recorded in the region and has triggered a red alert – the highest level of heat warning – from French meteorological authorities. The heatwave is expected to intensify, with some models predicting temperatures could surpass the current national record of 46.0°C set in 2019.
Health and Safety Warnings
Authorities have urged residents to take precautions, including staying hydrated, avoiding outdoor activities during peak heat hours, and checking on vulnerable individuals such as the elderly and those with pre-existing health conditions. Schools and public events have been canceled in affected areas, and cooling centers have been opened. The French health ministry has activated emergency protocols to manage heat-related illnesses.
Climate Change Context
This heatwave is part of a broader pattern of extreme weather events linked to climate change. Scientists have warned that such heatwaves are becoming more frequent and intense due to global warming. The red alert underscores the urgent need for adaptation measures and emissions reductions to mitigate future risks.
