High temperatures and possible heatwaves to return in France in August
After much of France recently enjoyed cooler temperatures following an
intense heatwave
in June and July, French forecasters have warned that August could bring hotter, drier weather, along with a possible heatwave.
It is still early for month-long predictions, and the various weather models do not yet agree on the intensity of the heat and the day it is set to start.

That said, most agree that the warmer temperatures should begin halfway through the first week of August, as the circulation of the dominant air mass shifts from air arriving from the northwest to air arriving from the Iberian Peninsula.

The French weather service,
Météo France
said in their
tendences
(trends) tab that for the first week of August (Monday, August 4th to Sunday, August 10th), "sunny summer weather is expected to prevail all week in the south. In the north, skies will remain variable until Wednesday, at which point temperatures will rise.
"The heat could become noticeable in the second half of the week," the weather service forecast.
Météo France forecaster François Jobard posted on Bluesky that people should "enjoy the relative coolness this week because significantly warmer weather awaits us next week."
Profitez bien de la relative fraîcheur de cette semaine car il se confirme que des conditions nettement plus chaudes nous attendent dès la semaine prochaine. Le mois d'août pourrait renouer avec un temps très chaud et sec, avec accentuation de la #sécheresse et hausse du risque de vague de chaleur.

Meanwhile, the European ECMWF model has predicted temperatures nearing 35C in southwest France as early as Wednesday, August 6th, with high temperatures affecting all of the southern half of France by Friday,
Le Parisien
reported.
Another weather service, La Chaîne Météo, also estimated that the heat index would rise at the end of next week toward seasonal averages.
The weather service estimated that "temperatures would rise between 5C-8C [during the first week of August], with temperatures above 30C south of the Loire, and highs reaching 36C to 37C in south-western France."
