CatchWindow fishing intelligence

Honolulu Harbor, HI Daily Water Report — October 4, 2026

Honolulu Harbor gets a qualified green light today: sailing, boating and fishing have the best setup, while paddlers should treat the afternoon gusts as the part of the forecast with teeth. The cleanest all-round window is early, from dawn through mid-morning. Winds are lighter before the day builds, and the sea reaches its calmest forecast level near 8 AM at 1.06 m. The late-morning high tide, 0.66 m at 11:34 AM, follows a very low 0.12 m predawn low, so expect a meaningful tide change through the morning rather than a static harbor day. Fishing’s 7.4/10 rating is supported by the 6:38-8:38 AM solunar major period, rising pressure, tide timing and manageable wind. Wildlife scores highest at 9/10, with the same early major period and low-tide proximity contributing to that model result. Sailing leads the practical activity scores at 7.8/10, with a representative northeast wind of 9 knots, though gusts are the caveat: they may reach 27.2 knots around 2 PM. Boating remains solid at 7.5/10, but the 1.1-1.2 m wave range includes 0.74 m short-period wind waves, which can make an otherwise reasonable ride feel busier than the headline swell suggests. Kayaking is a more conditional 6.2/10: workable early for experienced, prepared paddlers, but less appealing once gusts strengthen and the 1-6 PM rain window arrives. The 1.16 m sea state is driven by a modest 0.62 m south swell at 7.85 seconds plus those shorter wind waves. Marine water temperature is 27.5 C. The reported 26.54 km atmospheric visibility is good for seeing across the air, not a statement about underwater clarity. No diving score is available, so there is no diving recommendation here. Compared with yesterday’s CatchWindow estimates, fishing improves from 6.2, while sailing eases from 8.2 and boating is nearly unchanged from 7.6. Pressure is also higher and rising today, at 1016 hPa. Looking ahead, seas stay near 1.0-1.2 m through Wednesday before building to 1.2-1.4 m Thursday onward; rain chances rise notably midweek. Best bet: launch early, use the morning tide and lighter breeze, and be back in before the afternoon gusts start throwing their weight around.
