France braces for another intense heatwave exceeding 40°C

Paris – June 15, 2026: France is facing a new intense heatwave expected to begin around June 13, 2026. This heatwave follows the earliest and most severe heatwave that occurred in May this year. Southern France is expected to be especially affected, with temperatures anticipated to rise above 35°C. Cities like Toulouse and Bordeaux could see temperatures reaching between 41°C and 42°C. As the week progresses, the heat will spread northward, possibly reaching up to 39°C in Paris around June 20.

This heatwave is caused by a high-pressure system over Western Europe, which brings a mass of hot air from North Africa. Not only France but also Spain, Italy, Germany, and Ireland are experiencing high temperatures. Experts point out that such early and strong heatwaves may occur more frequently due to climate change. They warn that without strengthened existing climate protection measures, risks such as heatwaves, wildfires, and droughts will increase by 2050 or 2100.

Temperatures up to 40°C are expected in southern areas near the Spanish border. In northern regions and Paris, daily high temperatures may reach 39°C during the weekend around June 20, while the seasonal average temperature is about 23°C. Additionally, a “tropical night” phenomenon, where temperatures do not drop below 20°C at night, is expected in many areas. These weather conditions make nighttime rest difficult and increase health risks, especially for the elderly, children, and people with chronic illnesses.

This heatwave coincides with the national high school graduation exam (Baccalaureate) period, placing additional strain on many students. Authorities have issued heat warnings in several southern regions and advise residents to stay well hydrated, remain indoors in cool environments, and avoid physical activity during the hottest times of the day.

In the long term, experts suggest adaptation strategies to mitigate heatwave impacts. Examples include urban greening, the creation of green roofs, and improvements in building insulation. Such measures can reduce the adverse effects during prolonged heatwaves and contribute to enhancing the quality of life in affected areas.

Regarding these extreme weather conditions, the weather service (Météo-France) continuously urges caution. Authorities emphasize the importance of following health service recommendations to prevent health issues. It remains to be seen how well residents can prepare for the returning heatwave next week and what impact this heatwave will have on infrastructure and the environment.
