Grande Plage du Sillon Swimming Forecast
Saint-Malo · France
Grande Plage du Sillon scores 77/100 for swimming today at its best ability level (advanced). The beach faces NW. A sweeping 3 km urban Atlantic beach facing northwest, fully exposed to prevailing winds and swell, with a huge tidal range. The sandy beach-break has submerged reef slabs and rip currents; surfable waves need a large west-to-northwest swell and rarely arrive, so it mainly serves wind and kite sports. Kitesurfing is banned 10:00-20:00 (15 Jun-15 Sep) outside a 300 m launch corridor, and above 7 m depth. Lifeguards patrol July-August, 12:30-19:00.
