Boulogne-sur-Mer, France Daily Water Report — August 31, 2026

Today in Boulogne-sur-Mer, the water conditions are decidedly mixed, with sailing emerging as the top pick at an impressive 8.3 out of 10. The robust 17-knot winds from the WSW, gusting up to 37 knots, make for exhilarating sailing, but they also contribute to choppy waters that are less friendly for other activities. Boating and kayaking score low at 3.8 and 2.4, respectively, as the nearly 2-meter waves and brisk gusts create challenging conditions. Surfing fares better at 7.1, aided by the consistent wave height and period, though the wind direction might make it tricky for less experienced surfers. Diving is a fair bet today with a 6.1 score, thanks to decent underwater visibility and a comfortable sea surface temperature of 20.4°C, though the swell could add some complexity. Fishing scores a moderate 6.7, with solunar periods offering the best opportunities early morning and late afternoon, though the lack of tide data could mean some unpredictability. Compared to recent days, today's conditions are windier and rougher, with a noticeable drop in suitability for kayaking and boating. The past few days saw calmer winds and better scores for these activities, but today's conditions call for caution. Looking ahead, the winds are expected to calm down slightly in the coming days, with wave heights decreasing significantly by September 6. If you're planning your next outing, mark September 1 for a potentially smooth sailing experience with lower winds and moderate waves. For a memorable recommendation, if you're up for a thrilling ride, hit the sails today and let the wind guide your adventure across the lively waters of Boulogne-sur-Mer.
