On Météo France forecast cards, colors darken. Nevertheless, Light orange. Nevertheless, dark red, burgundy: from this Monday, August 11, temperatures will be breeked on a large part of mainland France, especially in the southwest of the country.

Therefore, the Minister continued, “The biggest risk is mainly for vulnerable people, the elderly, people over 65 who are isolated and may be victims of heat due to their underlying pathology”.

In addition, the second of the summer after that second heat wave summer intensified of June, Météo France placed 12 departments of the Southwest in red alert for “heat wave” from Monday noon, and until Tuesday, midnight. Nevertheless, This heat wave should be “Less intense and shorter than that of August 2003”, underlines the forecaster Christelle Ropert. Therefore, It is nonetheless exceptional.

Exceeding 40 degrees is nothing «normal», Even in the midst of summer, recalls the agroclimatologist Serge Zaka, “The planned temperatures [lundi] will be 14 to 17 ° C above average for an August 11 ». Similarly, “No, 43 ° C in Bordeaux it’s not summer, it’s hell, The weather site abounds. August second heat wave summer intensified normal in this city is 26-28 ° C ». Météo France confirms: the average maximum temperature of the Gironde prefecture, in August, between 1991 and 2020, is 27.6 degrees. And even if we find. in the past, cities that have punctually exceeded 40 ° C, it is the recurrence and multiplication of these peaks that are problematic.

As Météo France recalls, “The hottest five summers since 1900 have all occurred in the 21st century: 2003, 2022, 2018, 2023, 2019.” Could the current heat wave of August 2025 join the top 5?

The 2025 heat wave could even bring down the records of 2023 – like that of 42.4 degrees on August 23 in second heat wave summer intensified Toulouse. The absolute record in France, 46 ° C in Verargues in Hérault in June 2019, seems to be unattainable.

The heat wave will gradually extend into Ile-de-France. the Grand-Est, with temperatures less hot than those on Monday in Aquitaine, but still high. 38 degrees expected in Nîmes, Paris, Besançon, and even 36 degrees in Lille. In the southwest. barely refreshed by a wind from the Atlantic, it will still be very hot-between 38 and 40 degrees-but less than the previous days. The region is expected to go back on “orange” vigilance on Tuesday. apart from the Aude department plagued by a violent fire just mastered.

Not enough to discourage participants in the international pétanque second heat wave summer intensified competition, which takes place this year in Aveyron. In this department, placed in orange alert, campers installed for the occasion in the commune of Espalion suffer. “With the heat wave. the tent turns into a sweating chamber”, testifies to Libération Alicia, a 32 -year -old Montpellier, however used to heat.

The levels of vigilance take into account this “Local sensitivity of temperatures”. explains Damien Griffaut, of the Department of Operations for the forecast at Météo France. “South populations are more regularly exposed to hot episodes than in the North.” Thus. the heat wave alert thresholds diverge according to the departments: in Haute-Garonne, it must make 36 degrees during the day and 21 degrees at night, while in the English Channel, it is enough to reach 31 degrees per day and 18 degrees per night.

On this subject. the nights will be particularly second heat wave summer intensified burning throughout the country this week, especially in the north of the country, where night hours will be “Quite difficult to live”alert Christelle Ropert. From the night of Monday to Tuesday, “We will not go down under the 20 degrees in Paris”, she adds. The southwest, not spared, should not, however, be broken. Difficult also to sleep serenely Wednesday evening in Normandy, in Hauts-de-France and the Champagne-Ardenne region. A sharper refreshment should occur Thursday, before “A new warmer pulsation” Until the end of the weekend. Thunderstorms at the end of the week could end the 51st heat wave since 1947.
