Warm, sunny and a bit stormy

According to national weather forecaster Météo-France, we’re set to enjoy some early summer heat over the weekend, with temperatures, especially in the north of the country, closer to July than the end of May – thanks to an anticyclone hovering over Ireland.

While morning temperatures are expected to remain around normal for the the time of year, afternoon temperatures of between 20C to 25C are forecast for the afternoons in the northern half of the country , and 24C to 28C in the southern half – rising as high as 30C in areas such as the Gard, Vaucluse and Var.

Scattered storms and showers, particularly in the south, may punctuate the conditions on Saturday and Sunday, notably in Nouvelle Aquitaine, Auvergne-Rhône-Alpes and the interior of Provence-Alpes-Côte d’Azur.

The good news is the situation is not expected to change much in the first part of next week, as May turns to June. 

The weather will remain very sunny in the northern half of France, and slightly more unstable in the south, with sometimes stormy showers. Temperatures will remain at high levels, especially in the northern half where the maximums will often be close to the normal values ​​of early July.
