Boulogne-sur-Mer, France Daily Water Report — September 1, 2026

For those eyeing the waters of Boulogne-sur-Mer today, diving takes the crown with an impressive 8.3/10 score. With gentle WNW winds at 3 knots, rising to a maximum of 8.6 knots, and a serene wave height of 1.1 meters, conditions are prime for exploring beneath the surface. The sea surface temperature is a balmy 20.7°C, well above the seasonal average, making it a diver's delight. Fishing enthusiasts, you're in for a decent day too, scoring 7.7/10. The solunar major period from 3:48 to 5:48 AM has passed, but the afternoon window from 3:48 to 5:48 PM should offer a promising opportunity. The high chlorophyll levels suggest an active underwater scene, although this doesn't directly translate to fish activity. Surfers can find joy as well, with a 7.3/10 rating. The swell from 254 degrees at just under a meter might not be the biggest, but the consistent wave period of 6.05 seconds is enough to carve some enjoyable rides. The calmest waters will be around 5 PM, so timing your session then could be the ticket. Boaters and kayakers might find today's conditions a bit of a mixed bag, with scores of 6.5 and 5.8, respectively. The ocean current at 1 m/s towards 158 degrees could add a bit of a challenge, especially for kayakers. Sailing, however, is less favorable at 4.8/10, as the light winds don't offer much for a thrilling sail. Looking ahead, the weather holds steady with mild temperatures and manageable winds through the weekend, though wave heights will vary. For the best bet today, grab your diving gear and explore the clear and warm waters, where the conditions are set to make for a memorable underwater adventure.
