Les Dunes

Les Dunes is an exposed sandy beach break in the Les Sables-d’Olonne area, offering fairly consistent surf with both left and right waves. Surf is generally easiest to read and most favorable around high tide, with conditions often described as gentle/soft and suitable for progression, especially when the swell is modest. Windwise, the spot favors northeast winds for clean, offshore conditions. Typical wind ranges are described around 10–20 knots with medium reliability, and NE is identified as ideal for water-sports planning. While summer can often be flatter for surf, the break is still used year-round depending on swell and wind, with the best surfing months noted as March (in the surf-forecast dataset). For safety, the shoreline is exposed and can generate strong shore break at high tide, and rip currents can occur (notably near the southern end toward the estuary). Rocks are mentioned as a hazard that may require tide cover; a recommendation is to aim for a tide coefficient above 70 to help cover them, and to use a water entry from the small beach. Local guidance also emphasizes avoiding the break zone when moving toward the peak. In peak summer (July and August), water activity can be restricted to designated zones outside patrolled swimming areas, and crowds increase. Outside the summer peak, the same broad beach environment is also used for kitesurfing, windsurfing, and wingfoiling—particularly when winds are correctly aligned and the swell is manageable.
