Nawiliwili, HI Daily Water Report — September 6, 2026

Surfing is the day’s winner at Nawiliwili, scoring 8.4 out of 10, with diving close behind at 7.8. Kayaking at 2.9 and boating at 4.4 are the weak hands; those scores are not safety stamps, but they do say the water is working against small craft. Open-Meteo’s current conditions and forecast keep a northeasterly around 8 knots, ranging 7.8 to 12.8, with the sharpest gust, 27.8 knots, timed near 14:00. That afternoon spike is the main wind tax. Seas hold 2.3 to 2.6 meters on a 9.3-second period, with a 1.5-meter swell at 8.5 seconds from 79 degrees and shorter 0.9-meter wind waves. The calmest reading is still 2.28 meters near 08:00, so “calm” is a relative term. A 1 meter-per-second current toward 31 degrees will shove a hull or a paddle more than a casual glance at the breeze suggests. The sky stays fully overcast, with drizzle possible from midnight through evening even though the representative total is only 0.1 millimeters. Air sits near 23.8 C and feels like 26.3 C under 89 percent humidity; atmospheric visibility is 8.1 kilometers, which is not underwater clarity. NOAA CoastWatch puts marine SST at 27.2 C, 0.4 C above average. Pressure is 1010 hPa and falling. NOAA tides run a 0.06-meter low at 04:53, a 0.69-meter high at 12:55, and a 0.16-meter low at 20:28. Solunar majors fall 07:56–09:56 and 19:56–21:56. Fishing only reaches 5.6, well off the 8.5 marks from late August, with falling pressure and today’s wind in that score. Sailing at 6.7 is down from 8.6 yesterday as cloud and the wave field weigh on it. Wildlife sits at 6.1. Diving holds near the 7.7–7.8 range of the last few days. Tomorrow and Monday turn heavier: peak winds above 22 knots, near-certain rain, and seas building toward 5.5 meters. By the 9th, waves ease to 1.7–2.4 meters and winds drop under 7 knots, with a quieter stretch through the 12th. Best bet: take the morning swell if you surf, and leave the kayak on the rack.
