Five departments in southern and southeastern France have been placed under an orange-level weather warning for heat today as Météo France warns of several days of very high temperatures.
The departments are: Pyrénées-Orientales, Ardèche, Drôme, Gard and Vaucluse, and 10 further departments surrounding them are also under yellow canicule warnings.
Last night (July 31), it was cool over the Languedoc-Roussillon and Rhône valley, but at 05:00 it was 27.2C in Perpignan, 24.6C in Nîmes-Courbessac and 25.5C in Avignon.
Temperatures are expected to rise throughout today and tomorrow, reaching 35-38C in the areas under an orange alert and 39C in some areas of Gard.
In the northern half of the country, temperatures should be in the region of 30-34C, apart from in Brittany and around the Channel, where they are expected to remain below 30C.
The peak of the heat is set to arrive on Wednesday (August 3), with highs of 39-40C in the south west.
Les #FortesChaleurs reviennent dès demain.

“The anticyclone from the Azores, responsible for the July heatwave, is returning to France,” Météo France forecaster Jean-Yves Choplin has said.
“In the north of the country, the episode should be short, with the return of ‘fresher’ air from the north west on Thursday and Friday. In the south, the hot air will linger for longer, especially in the south east.”
However, nowhere in France should remain under the high temperatures for as long as parts of the south west and south east did in July.
Météo France has warned of a “very high risk of fires” along the Mediterranean coastline, because of the appearance of “quite strong” mistral and tramontane winds and “conditions remaining very hot and dry across vegetation growing more and more fragile”.
To limit the risk of wildfires, all of Vaucluse’s forests – and several of Bouches-du-Rhône’s – have been closed to the public
France has already seen two heatwaves this year, in June and July, the latter being the third most intense and fifth longest since 1947.
