CatchWindow fishing intelligence

New Haven, CT Daily Water Report — September 6, 2026

New Haven gets a clear yes for small-craft time and a qualified yes for getting in the water: boating leads the board at 8.4/10, with diving 7.6, sailing and wildlife 7.2, and kayaking 7.0. The sea state is the headline—just 0.1 to 0.3 meters of wave height, with a representative 0.14 meters—so this is a notably tidy day by coastal standards, not a surf day in disguise. The best all-around daylight window runs from dawn through the afternoon, when dry weather, cloud-free skies, and generally light NNW winds of 2.5 to 7.6 knots support easy boating, paddling, and dive logistics. Air temperatures climb into the low 20s C, while marine SST is 23.4 C, slightly above average by 0.4 C. Winds are not entirely asleep, though: gusts can reach the high teens, with the strongest forecast near 23:00. That makes late-day return planning worth more attention than the modest average wind suggests. The ocean current is 0.5 m/s toward the east, another reason to keep route and drift planning deliberate rather than letting the flat surface sell you a false sense of simplicity. Anglers have a respectable 6.6/10 day. The stronger solunar major period is 07:54 to 09:54, with a second after sunset from 19:54 to 21:54; the afternoon minor period runs 14:24 to 15:24. Rising pressure near 1017 hPa and light wind are constructive inputs to that score, but no tide data are available, so timing cannot be refined around tidal movement. The reported chlorophyll is very high and indicates bloom conditions; it is not a read on fish or wildlife activity. Divers should likewise separate the excellent surface calm from any assumption about underwater visibility, which is not supplied. Surfing remains a 4.5/10 proposition: the short, tiny swell and low waves are simply too small to make much of a case. Compared with recent CatchWindow scores, boating matches yesterday’s 8.4, while sailing improves sharply from 5.4 as the wind-and-wave balance becomes more workable. Monday and Tuesday stay warm, dry, and low-wave, though winds increase Wednesday and Thursday alongside waves up to 0.7 meters. Best bet: launch early, fish the 07:54–09:54 major window, and enjoy the glassy water before the evening gusts remember they have a job.
