Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
When the buoys are in place, you enter and leave the water via kite lane 3 east of the slipway at rue Casimir Delavigne, or via the shared lane in front of the base nautique of Colleville; in the lanes, 5 knots maximum and transit only. Municipal order ARR2026-188 applies from 15 June to 15 September. Source: préfecture maritime, arrêtés 65/2026 and 44/2025.
The open water at Ouistreham (Riva-Bella) faces N (11°). The safest wind directions to get on the water here are north, northeast and northwest (onshore or cross-onshore). With the wind from the east, southeast, southwest and west, it runs cross to cross-offshore: doable, but mind your position and don't go alone. With the wind from the south, it blows offshore and is dangerous: you'll be pushed off the beach onto open water (no-go).
