Le Château d'Oléron is located on the eastern shore of a sheltered bay on Île d'Oléron in southwestern France. The spot features a northeast-facing coastline with shallow bay waters, extensive aquaculture operations, and residential development. Water conditions are generally mild with average waves of 1.16m and water temperatures around 14°C. The bay configuration provides protection from heavy swell but limits wind effectiveness, reflected in the low 22.6% wind reliability. Best conditions occur with northwest winds (315°) that provide side-shore flow parallel to the coast. The shallow bay waters and numerous structures make this primarily a beginner to early-intermediate spot, suitable for riders seeking calm, protected conditions rather than challenging waves. Kiters should exercise caution regarding shallow depths, farm installations, and varying bottom composition. The location works best during periods of consistent Atlantic wind, though average wind speed of 9.4 knots suggests light to moderate conditions are typical.
