France’s fourth heatwave of the year so far is set to begin today (Monday, August 8) in the south, before spreading across the whole country and lasting until next weekend.
This comes just after the high temperatures linked to the summer’s third heatwave dropped slightly over last weekend.
This week, everywhere south of the Loire river should expect temperatures of around 36C-40C during the day, and 20C or more at night. In the west, highs will fluctuate between 35C and 39C, and in the north west it will be 30-34C.
North of the Loire, temperatures should be made to feel cooler by the wind.
This morning, the departments of Gard and Vaucluse are under an amber warning for high temperatures, with yellow alerts having been applied to much of the southern quarter of the country, from the Atlantic to the Mediterranean coastline.
This fourth heatwave is the result of an anticyclone lingering over western Europe, preventing other weather systems from reaching it. This is leading some meteorologists to state that this latest episode is simply a continuation of the third heatwave.
National weather forecasting service Météo France is not yet qualifying the hot spell as a canicule – when temperatures remain above a certain threshold during the day and at night for at least three days – but it is “probable” that this will occur.
“We are talking about a heatwave which is lasting nearly 15 days, it’s a very long time,” Météo France forecaster François Jobard told Franceinfo.
En 2nde moitié de semaine, les températures seront de + en + chaudes sur l'ensemble du pays. Nouvel épisode de #canicule probable sur de nombreuses régions avec des températures qui resteront très élevées jusqu'au week-end prochain.

Temperatures “will rise day by day to reach very high levels, even in the northern half [of France],” Mr Jobard added.
Friday (August 12) is expected to be the hottest day, with highs of 35C in Paris, as opposed to 30C today.
However, this heatwave episode will not be as intense as that which occurred in July, where temperature records were broken across several French regions.
The hot weather will continue contributing to the dryness of France’s soils. “There will be stormy rain showers, but normally on higher ground and in Provence-Alpes-Côte d’Azur,” Mr Jobard said.
“That will help the situation on a very local level, but across the vast majority of the country, it will remain desperately dry.
“The sun and the wind dry [things out]; the ground will lose even more water this week.”
This comes after July was revealed to be the second driest since records began.
