France is facing one of its most severe heat waves in decades, with authorities reporting 40 drowning deaths since June 18 as soaring temperatures push millions to seek relief in rivers, lakes, and coastal waters. Prime Minister Sebastien Lecornu confirmed the fatalities during a ministerial crisis meeting, while officials warned that the combination of extreme heat and increased water activity has significantly raised the risk of deadly accidents.
The country also experienced its hottest night on record since 1947, with minimum temperatures averaging 21.6°C (70.9°F) nationwide. France’s national average daytime temperature reached 29.2°C (84.6°F), setting a new June record, according to Meteo-France. On Tuesday, 54 departments were placed under the highest red heat alert, while another 35 remained under orange alert, with temperatures expected to climb as high as 40°C (104°F).
The extreme weather has also heightened wildfire concerns, with 28 departments currently facing a high wildfire risk, a figure expected to rise to 34 departments. Emergency services remain on high alert as authorities urge residents to avoid unnecessary outdoor activities, stay hydrated, and follow official safety guidance.
The heat wave extends far beyond France. The United Kingdom has issued a rare Red Extreme Heat Warning, warning that June temperature records could be broken. Spain is expecting temperatures up to 44°C (111°F) under widespread red and orange alerts, while Portugal, Italy, and Belgium are also preparing for prolonged periods of dangerous heat.
Meteorologists warn that this widespread European heat wave could continue for several days, increasing risks of heat-related illnesses, wildfires, and water accidents. Officials across the continent are encouraging people to take extra precautions as climate experts point to increasingly frequent and intense extreme weather events.
