Summer no longer knocks at the door – it breaks it down directly.
France is experiencing a heatwave at the end of May that even leaves the most experienced meteorologists astonished. While many people are still thinking about spring jackets, changeable days, and cool mornings, temperatures in the west of the country are already rising to values normally seen only in the height of summer. The most affected regions are those along the Atlantic coast and in the west of the country. Since Tuesday, an exceptional weather situation has been recorded with temperatures well above the May standards.
In cities such as Nantes, Bordeaux, or Lyon, the thermometer reaches 34-35 degrees. Even in usually temperate regions, the weather map suddenly shows an intense orange to red. Heatwave warnings are in effect for numerous departments. And for now, there is no end in sight for this wave.
What is particularly remarkable is the timing.
At the end of May in France, temperatures above 30 degrees are normally an exception. This time, however, experts are talking about a historic event. The air masses come from North Africa and are pushed towards Western Europe by stable high pressure. Meteorologists speak of a so-called “heat dome.” It works like a lid on the atmosphere — hot air accumulates, rain is missing, and temperatures increase day after day.
Over 350 weather stations have already recorded new temperature records for the month of May. This shows how unusual the situation is. Many elderly people remember hot summers like those of 2003 or 2019, but a heat wave this early is almost surreal even for France. “It’s really strong,” is often heard in outdoor cafes or at train stations.
The health risks now become a priority.
Summer heat is familiar to many — the body prepares. But at the end of May, this adaptation is often still completely missing. Homes accumulate more heat, schools and offices rarely have air conditioning, and many underestimate the impact. The most vulnerable people, such as the elderly, children, construction workers, or athletes, risk quickly running out of strength.
Authorities therefore recommend avoiding physical exertion, drinking enough water, and regularly checking on people at risk. Especially in cities, heat accumulates among concrete, asphalt, and densely built streets like in an oven.
Behind this current situation, however, there is more than just an exceptional spring.
Climate experts have observed for years that heat waves are arriving earlier, lasting longer, and are more intense. What used to be an extreme event is increasingly becoming a new normal. The classic summer heat is shifting forward on the calendar — one step at a time, year after year.
France is getting a taste in May of a summer that will generate many discussions about air conditioning, urban planning, water supply, and the question of whether Europe is truly prepared for these new temperatures.
Because this week clearly demonstrates one thing: the old idea of a mild spring is faltering.
