The main wind is E-NE all the year. Windy season starts in December (NE wind), but February is probably the best time to be there, because then the wind is guaranteed and comes from the East. Wind is lighter in December (3-5 Bft.) and gets stronger during the season.
The spot is right by the N4. Coming from Gosier, the spot is located directly after about 5km on the right. You can't miss it. After the supermarkets (Match) and the last houses of the suburb St. Felix, the N4 turns left away from the coast and starts climbing a steep hill. There is a gravel track right before the turn that leads to the beach, which may be crowded at the weekends. Coming from St.Anne: After the village Mare Gaillard you can see the beach when you come down the hill. Turning off is a little tricky because the sharp turn into the gravel track you have to carry out lies right after the right-hand bend at the foot of the hill.
