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 right and take the street along the water until you pass the harbor. Here the beach starts and stretches for 1.3 km.
