France is experiencing a historic heatwave, record-high temperatures and the first deaths have been reported.

Paris – 23 June 2026: France is currently experiencing an unusually early and intense heatwave that began on 17 June and is expected to last at least until the end of June. On 23 June, the national average temperature reached 29.8°C, setting an all-time record.

The extreme heat has led to the closure of many schools and suspension of train services. In addition, at least 40 people drowned while cooling off in rivers and lakes. Of particular concern are areas along the Loire and Rhône rivers, where strong currents and unmonitored swimming spots have led to multiple incidents.

In response to the heatwave, 54 departments issued the highest-level red alerts, and another 35 departments were under orange alerts. These measures affect more than 90% of the French population. The government has launched emergency response plans, with special protection for groups vulnerable to high temperatures, such as the elderly, children and people with chronic illnesses. Volunteer organizations have also coordinated rescue efforts, distributing drinking water and assisting those affected.

The heatwave has also affected infrastructure: rail services have experienced delays and suspensions due to high temperatures. Several nuclear power plants have had to reduce output because the river water used for cooling has warmed unusually. State energy company EDF has reported failures at the Golfech plant in the south and at Blayais, Bugey and Saint-Alban in the east. Reduced power supply increases the risk of energy shortages and calls have been made for consumers to save electricity.

Climate scientists say this heatwave clearly reflects the trend of global warming. Their calculations show measured temperatures up to 4°C higher than they would have been without human-caused climate change. These events underscore the urgency of accelerating adaptation and protection measures against extreme weather.

Officials advise the public to avoid strenuous activity during high temperatures, stay well hydrated, seek cool places and closely follow warning information. Many cities have set up dedicated cooling centers to provide safe relief for people without air conditioning.

This particular heatwave is putting pressure not only on health and infrastructure but also poses drought challenges for agriculture. Experts are calling for sustainable water use and adjustments to planting practices to strengthen preparedness for more frequent and severe heat events. The current situation has significantly raised awareness in France of the need for climate adaptation measures.
