Historic heatwave in France, record temperatures and first fatalities reported

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

The sharp temperature rise has led to the closure of many schools and suspension of train services. Furthermore, at least 40 deaths by drowning have been reported in rivers and lakes, as many people tried to cool off in unsupervised waters. This is particularly concerning in regions around the Loire and Rhône rivers, where strong currents and a lack of supervised bathing areas have caused multiple accidents.

In response to the heatwave, the highest alert level, red warning, has been issued in 54 departments, with 35 additional departments under orange warning. These measures affect over 90% of France’s population. Authorities have activated emergency plans to specifically protect vulnerable groups, such as the elderly, children, and individuals with chronic illnesses. Volunteer organizations are also coordinating activities to distribute water and support those affected.

The heatwave is also impacting infrastructure. Railways are experiencing delays and cancellations due to high temperatures. Additionally, because the water temperatures in rivers used for cooling are higher than usual, several nuclear power plants are limiting their output. The state energy company EDF has already reported disruptions at the Golfech plant in the south and the Bugey, Saint-Alban, and Blayais plants in the east. This reduction in power production increases the risk of energy shortages, leading to calls for energy conservation among consumers.

Climate researchers view this heatwave as a clear sign of advancing global warming. Their calculations indicate that the observed temperatures are up to 4°C higher than they would be without anthropogenic climate change. This event highlights the urgency of adaptation and protection measures against extreme weather conditions.

Authorities recommend that the public avoid strenuous exercise during the heatwave, stay well hydrated, spend time in cool places, and pay attention to warnings. In several cities, special heatstroke support centers have been set up as safe shelters for people without air conditioning.

This abnormal heatwave is placing a burden not only on health and infrastructure but also on agriculture suffering from drought. Experts call for strengthened sustainable water use and adaptive farming methods to prepare for frequent and intense heatwaves. This situation is significantly changing awareness of climate adaptation measures within France.
