Waikiki, HI Daily Water Report — September 5, 2026

Surfing is the day’s winner at Waikiki, an 8.5 on wave height, period, swell direction, and wind, with diving right behind at 8.3. If you get one clean window, take it before midday. A south swell of 1.42 meters at nearly nine seconds sits under overall seas of 1.7 to 1.9 meters, and the representative northeast breeze is only about 7 knots. That is the setup those two scores are built on. The tradeoff arrives later: wind ranges 6.9 to 11.6 knots, but the strongest gust is 30.1 knots at 15:00, enough to roughen a session that started honest. Kayaking is the miss at 4.3, and boating only 6.2. Both weigh wind, waves, current, and precipitation, and a 0.7 meter-per-second current toward 256 degrees is no small current. Sailing still holds 7.7, a clear step down from yesterday’s 9.1 when the wind picture was kinder. Fishing is a middling 6.6, off yesterday’s 6.9 and well below the 8-range earlier in the week, as falling pressure near 1011 hPa works through that score’s mix of solunar timing, tide state, pressure, wind, and available clarity. Wildlife sits at 7.3. Tides run 0.07 meters at 03:48, 0.68 meters at 12:04, and 0.12 meters at 19:59. The morning solunar major, 06:46 to 08:46, follows sunrise at 06:17 and is the more useful stretch before those afternoon gusts. Seas are calmest near 05:00, which here still means 1.7 meters. Air runs 23.2 to 28.7 C under 25 percent cloud and about 15 kilometers of atmospheric visibility; a rain window is listed 04:00 to 17:00 even with representative precipitation at 0 millimeters. Marine SST is 26.7 C, 0.9 C above average. Chlorophyll is 0.07 mg/m3, oligotrophic blue water, and that is not a fishing or wildlife cue. Surfing has cooled from the 9.3–9.4 marks of September 1–3 but matches yesterday; diving has lived in the mid-8s. Looking ahead, seas build to 1.9–2.1 meters on the 6th, 2.1–3.0 on the 7th, and as high as 3.4 on the 8th, with rain chances into the 70s, before they ease toward 1.1–1.4 meters by the 10th. Best bet: take the morning south swell and be done before 15:00 tries to edit the day.
