Temperatures should reach 35°C in Agen or Mont-de-Marsan, with a gradual rise in the thermometer throughout the week, and a heat peak expected on Friday. All under a sun that no cloud will disturb. Before the storms return next weekend.
In the rest of France, where temperatures above 30° in the followingnoon are expected almost everywhere, only the Rhône valley and the Toulouse region will experience a heat wave comparable to the Aquitaine basin.
According to Frédéric Nathan, forecaster at Météo-France, this episode of high heat over several days, from mid-June, is “extremely early”. Between Thursday and Saturday, very high temperatures of 35°C to 38°C are expected on the southern half, and the mercury might even approach 40°C locally. Minimum temperatures should not drop below 20°C at night.
This heat wave, linked to a localized depression between the Azores and Madeira which favors the upwelling of hot air over Western Europe, should arrive on Tuesday evening in the extreme south of the country, before spreading to the whole of the country on Wednesday. the southern half.
The forecasts do not currently allow us to say that this episode will formally be a heat wave, which meets specific criteria (period of intense and lasting heat, day and night, over an extended period of more than three days in general ). However, it is possible that the heat wave threshold will be reached or even exceeded in certain departments.
The multiplication and intensification of heat waves and heat waves are the most obvious manifestations of global warming caused by human activities.
This week’s heat wave comes following a particularly hot and dry spring which caused drought in the soil over a large part of France which raises fears for the crops.
