Last week, France experienced an unprecedented heatwave episode. On Friday June 17, no less than 70 departments in France were placed on red or orange vigilance by Météo France, and 40°C were reached in many departments, from north to south.

The phenomenon is worrying and climatologists are warning: periods of high heat could become more and more frequent. And if some regions could be spared, such as Normandy, Hauts-de-France and Brittany, in others, the summers promise to be suffocating.

To fight against this inevitable temperature, Prime Minister Elisabeth Borne recently announced the launch of a program of “renaturation of cities”, with an investment of 500 million euros.

In 2021, according to a ranking by the Internet user, the regions of France where it was the hottest were the following:

Unsurprisingly, therefore, it is in the south of France that the temperatures are often the mildest. But with global warming, no area is now safe from heat waves.

These should be more and more frequent over the next few years. And some territories will be even less spared than others. Le Figaro has thus compiled the projections of climatologists for 70 French cities, in order to establish the ranking of those which will be hard hit by the heat wave in 2040.
