However, the intensity of this episode (maximum peak) "promises to be less than in 2019 and 2003, and its duration less than in 2003", specifies the organization. The summer of 2019 was marked by two exceptional heat waves and an absolute record, at 46 ° C.

Friday morning, cloud banks will circulate on the Atlantic coast, driven by a light westerly wind, and may give a few drops locally. In the afternoon, this partly cloudy sky will stretch from Brittany and Cotentin to New Aquitaine, but the impression will remain in good weather, under heavy heat.
