CatchWindow fishing intelligence

Boulogne-sur-Mer, France Daily Water Report — October 7, 2026

Verdict: a very good harbor-water day, especially for paddlers and boaters who get out early and are back before the late-day deterioration. Kayaking leads the board at 9.2/10 and boating follows at 8.7/10, supported by light ENE wind around 3 knots, a modest 0.14 m sea at the calmest part of the day, and a weak west-setting current near 0.06 m/s. Those are favorable working conditions, not a blank cheque: the forecast builds from the overnight low, with waves ranging as high as 1.2 m and gusts reaching 34.2 knots at 23:00. The cleanest practical window is dawn through late morning. First light arrives around 07:31, sunrise is 08:04, and the light winds should make harbor handling, short boat runs, and paddle sessions comparatively straightforward. The 10:13–12:13 solunar major period is the best timing cue for anglers, though fishing is a middling 5.9/10 rather than a promise of action. Pressure is falling from around 1010 hPa, and no tide data are available, so plan around the conditions you can see rather than pretending the missing tide clock is in your pocket. Diving rates 7.6/10, helped by low early wave energy and an 18.8 C marine sea-surface temperature, but the 33 km atmospheric visibility forecast is not an underwater-visibility reading. Cloud cover is heavy, around 90%, and rain is forecast from 15:00 to 22:00; that afternoon shift, plus the rising wind and eventual strong gusts, makes an early finish the sensible move. Sailing is only 4.6/10: there may be enough breeze later, but the gust spread and building sea make it less tidy than the morning’s calmer options. Compared with the last two days, boating remains strong, while kayaking improves and diving slips from 8.8/10 as pressure has fallen sharply from Monday’s 1020.2 hPa. The next few days look rougher: waves reach 1.4 m Thursday, potentially 2.4 m Friday, and remain 1.4–2.1 m Saturday before easing Sunday and Monday. Best bet: launch early, enjoy the harbor while it is glassier, and let the evening gusts have the last word.
