Certain parts of the country, namely around Toulouse and the south west, localised temperatures could reach up to 33C. North-eastern France is also expected to see high temperatures this weekend, with Strasbourg forecast to reach up to 30C.

On Saturday, apart from some clouds and possible stormy weather in northern France along the Channel coastline, much of the country is expected to have a sunny day with warm weather. 

As for Sunday – the first day of October – forecasters expect to see more temperature records broken as a ‘heat dome’ moves across France.

Weather forecaster Météo Express predicted that the heat will stick around until at least Monday, particularly in the southern half of the country.

As for the Atlantic coast, water temperatures may be between 17C and 21C, and the Mediterranean will likely be even warmer with expected averages of 22C to 23C.
