France records hottest summer ever amid heatwaves and wildfires

France has experienced its hottest summer ever recorded since measurements began in 1900, according to Ecological Transition Minister Monique Barbut. The summer of 2026 was characterized by intense heatwaves, droughts, and massive wildfires, including those in the Gironde region. One heatwave in late June set a record for intensity, while another lasting from late July to August tied the record for the longest heatwave at 23 days.

The extreme weather has significantly impacted the nation's infrastructure, particularly the railway sector. Heat-related issues such as buckled rails, sagging overhead lines, and blocked air conditioning have caused widespread disruptions. These climate-driven events, including landslides and heatwaves, resulted in a revenue loss of over 100 million euros for the SNCF during the first half of the year.

In response, Minister Barbut is tasked with accelerating the National Climate Change Adaptation Plan. She has promised to present new conclusions and a five-year financing plan by the end of September. Experts warn that even hotter summers are anticipated throughout the 2030s, necessitating long-term adaptation strategies for the country's transport and ecological ecosystems.
