The very strong heat continues to spread in France. Charente-Maritime is in turn subject to heat wave orange vigilance, bringing the number of departments concerned to 50. Temperatures will therefore remain very high on Monday with heat which will further intensify over the southern half to the center of the country, according to the latest forecasts from Météo-France.
In Occitania, around the Rhône valley, on the shores of the PACA region and Corsica, nighttime temperatures will not drop below 17 to 22 degrees in general and will sometimes remain between 22 and 26 degrees. During the hottest hours, 28 to 32 degrees should be expected from Pays de Loire to Ile-de-France, to the east of Hauts-de-France, Champagne-Ardenne and Lorraine.
Some absolute records “are at risk of being broken”
Elsewhere, temperatures will soar, between 33 and 37 degrees, up to 37 to 40 degrees in Occitania and from Rhône-Alpes to Provence and Var. It will be locally 41°C in the shade, especially between Drôme, Ardèche, northern Gard and Vaucluse.
Above all, the day of this Monday could not be the hottest of the week. “The heat wave peak is expected between Tuesday and Wednesday. Some absolute records are likely to be broken, especially on Tuesday towards the Rhone Valley, with 40 to 42 degrees expected. The duration and intensity of this episode could require an evolution of vigilance towards a worsening, especially in Drôme/Ardèche (or even Vaucluse and Gard)” according to Météo-France. However, the public establishment specifies that “this eventuality still needs to be confirmed”.
Relative freshness in Brittany
However, not everyone will be so hot. Brittany and the departments bordering the Channel will thus benefit from a relatively cool atmosphere this Monday. Temperatures will be between 13 and 16 degrees in the morning and will reach 23 to 27 in the afternoon, locally 20 to 22 on the coast. On the sky side, greyness and morning mists will give way to long sunny periods.
