How are those small barge cruises in France?

Question

whats the tempeture in Sept. in the south of France

Answer 1

The weather is very nice. It's the best time for holidays in the south of France,

In July-August,  too many people........All the North of europe is in the south of France

25°C in all the south, sometimes more (28-30) (Nice = L.A for the weather).)

Sunny weather, but some storms can break the tempeture
