Boulogne-sur-Mer, France Daily Water Report — August 25, 2026

Today in Boulogne-sur-Mer, sailing enthusiasts will find the conditions particularly inviting, with a score of 8.2 out of 10. The steady easterly wind, peaking at 10 knots with gusts up to 20 knots, provides a robust breeze for a satisfying day on the water. The waves are gentle, ranging from 0.3 to 0.5 meters, with the calmest period around 11:00, making this morning an optimal window for a smooth sailing experience. Divers can also enjoy a decent day, though not as stellar as yesterday, with a score of 7.6. The water temperature is a comfortable 20.6°C, and the visibility is excellent at nearly 30 kilometers. However, the barometric pressure is on a slight decline at 1012 hPa, which may affect clarity as the day progresses. Fishing scores have dipped slightly to 6, influenced by the solunar periods peaking later in the day and the lack of tide data. Anglers should aim for the major solunar periods between 09:16-11:16 and 21:16-23:16 for the best chances, though the absence of tidal information could make the catch a bit unpredictable. Kayakers and surfers might find today less appealing, with scores of 4.6 and 4.9, respectively. The wind and wave conditions aren't quite in their favor, and the relatively short wave period of 4.4 seconds doesn't offer the best ride for surfers. Meanwhile, the wildlife score of 6.5 suggests some activity, particularly during the solunar periods, though it's not the standout feature today. Looking ahead, the weather is set to become more dynamic, with increasing chances of rain and stronger winds towards the end of the week. By August 29, expect the waves to rise significantly, hitting up to 1.4 meters, which might make for thrilling conditions for the more adventurous sailors and surfers. For today, if you’re seeking the best bet, grab your sails and enjoy the harbor’s breeze before the weather turns.
