Matin
The weather is fine with barely veiled sunshine in the northwest. Sea mists are locally present on the tip of Brittany and on the plains of the southwest. Then, the sun will eventually break through. A certain greyness could remain quite persistent however in Finistère.
Minimum temperatures are rising, and the cool weather will soon be forgotten. It is generally 12 to 15°C (occasionally 10°C in the eastern countryside) with 18 to 25°C on the Mediterranean coast.
Afternoon
The heat is imposed under a blazing sun, without wind. A real day of midsummer. The only downsides will be again a few storms in the mountains (border Alps), Corsican mountains and Andorra. The western sky is slowly clouding over.
Temperatures are high, especially in the east and central-east. For example, we expect:
28°C in Rennes and Nantes
29°C in Lille
30°C in Strasbourg
31°C in Paris and Bordeaux
33°C in Toulouse
and 34°C in Lyon, the hottest city in France
Soirée
Warm and summery night. Cooler air will rise over the Atlantic arc and move inland during the night. But it will be warm for a long time in the eastern half.
Further trend
The heat will be maintained until next week, including for the back to school. especially in the east. On Thursday and Friday, thunderstorms will break out in the southwest, while remaining quite scattered. But this stormy trend will strengthen for this week-end.
