A man made channel, specially for speed windsurfing, about 1km long, has been build. Perfectly flat water. On the ocean side you can find nice speed conditions as well, but winds will be offshore then.
In summer season you don't need a wetsuit. But you could take it with you because it could be a little colder. The water was something like 25°C the air was 35°C but it can be 20°C as well the season is from June to August. You can surf off-season as well but a wetsuit is needed. Air: summer 25-35°C, winter 5-15°C. Water: summer 20-25°C, winter 5-10°C. Sometimes there is a cold current, so a wetsuit is also in the summer recommended.
From Nimes get onto D570 and it ends in Saintes-Maries-de-la-Mer. Drive to the water and turn left and take the street along the water until you see the speed channel.
