CatchWindow fishing intelligence

Boulogne-sur-Mer, France Daily Water Report — September 2, 2026

Today in Boulogne-sur-Mer, diving takes the crown with a stellar 8.7 out of 10, making it the top choice for water enthusiasts. With calm waves peaking at 0.9 meters and a pleasant sea surface temperature of 19.8°C, visibility should be quite inviting below the surface. Anglers and boaters also have a decent window, scoring 7.4 and 7.6 respectively. The solunar periods suggest early morning and late afternoon as prime times for fishing, although the lack of tide data means you'll need to rely on your instincts and experience. Surfing, on the other hand, is a bit of a mixed bag today, rated at 5.8. The swell is modest at 0.52 meters, coming from the southwest, which could make for some tricky waves. Winds are mild at 4 knots from the WSW, but watch for gusts picking up to 11 knots, especially later in the evening when they could hit 24.3 knots. Compared to recent days, today's conditions are a step up for boaters and kayakers. Yesterday's boating score was a 6.5, so today's 7.6 is a nice improvement. Kayakers will also find smoother paddling with a score of 7.1, up from 5.8. The air temperatures range from a comfortable 16.9 to 19.6°C, with a bit of cloud cover but no rain expected until a brief window between 13:00 and 14:00. Looking ahead, the weekend brings slightly choppier seas with waves rising to 1.8 meters by Sunday, so make the most of today's relatively calm waters. If you're planning an outing, diving is your best bet—it's not just a good day, it's a great one.
