France may experience its third heatwave of the year next week, with temperatures already rising over the weekend.
The heat is expected to intensify on Monday and Tuesday (August 1 and 2), before peaking on Wednesday, with the highest temperatures being felt in the south of the country.
“In the southwesterly quarter [of France] it will approach 40C again,” SportRizer meteorologist Yann Amice told Ouest France.
Il faudra surveiller la deuxième semaine d'août, elle-aussi potentiellement très chaude en direction du sud comme le montre les diagrammes de #Marseille et #Toulouse.

Even if they do not reach the 40C threshold, temperatures will be around 35C across the southern half of France, and around 30C in the northern half.
The only place not included in this hot spell will be the area around the Channel, where temperatures will be warm but not unusual for this time of year.
La vague de chaleur de la semaine prochaine sera plus intense entre lundi et mercredi avant de régresser vers l'Est jeudi selon les projections. Des pointes proches de 40°C seront possibles au sud de la Loire ! pic.twitter.com/jVCUC7Uquh— Anthony Grillon (@AnthoGrillon) July 29, 2022
An anticyclone and a heat dome
The high temperatures will be brought about by an anticyclone in the Atlantic, which is warming the air over France and creating a heat dome.
However, in contrast to previous heatwaves, this weather system is not being compounded by hot air moving up from the Sahara, so the temperatures should not be as intense as they were, for example, during the June heatwave.
The heat should abate before next weekend, when storms are expected to arrive in France.
However, Mr Amice added that “modelling shows the anticyclone move towards the west of Ireland,” and that “by putting itself in that position, it will block any possible arrival” of fresher air from the west.
Therefore, temperatures could rise again the week after next.
Forecasting service Chaîne Météo has said that this hot spell could be a sign of things to come over August, stating that the month looks set to bring with it “intense heat and dryness”.
