Baie de Gatseau is a shallow, sheltered bay on France's Atlantic coast near the Gironde estuary. The coastline faces southeast, with a sandy beach backed by dense maritime pine forest. The turquoise water indicates significant sediment load from the nearby river system, creating a murky bay environment with gentle, rolling conditions rather than defined wave breaks. This is primarily a wave-riding spot with modest fetch and protection from the surrounding landmass. The shallow sandy bottom makes it suitable for beginners, with relatively forgiving conditions. Best wind direction is northeast, providing side-shore conditions parallel to the coast. Infrastructure visible at the northern end suggests port activity, so awareness of boat traffic is necessary. Average wind reliability is low at 11.7%, making this a fair-weather spot dependent on Atlantic wind patterns. Water temperatures average around 14°C, requiring appropriate thermal protection. The combination of shallow water, sand bottom, and limited exposure makes this suitable for progression-level kiters rather than advanced wave riders seeking challenging conditions.
