Honolulu Harbor, HI Daily Water Report — August 31, 2026

Today, Honolulu Harbor presents a mixed bag of opportunities and challenges on the water. Sailing enthusiasts will find this to be a stellar day with a score of 9.2 out of 10, thanks to consistent ENE winds averaging 12 knots, ideal for a smooth sail. Surfers are also in for a treat, scoring an 8.9, with wave heights around 1.32 meters and a manageable swell direction from 185 degrees. Divers can expect great conditions, scoring an impressive 8.6, with low wind and wave influence making for a safe and clear underwater experience. However, those planning on kayaking might want to reconsider, as the score dips to 3.4 due to the choppy wind waves at 0.88 meters and a brisk current moving at 1.3 m/s toward 262 degrees. Boaters see a moderate score of 5.3; while not ideal, it’s manageable for those with experience navigating these conditions. Fishing scores a solid 7.4, with solunar periods favoring early morning and afternoon efforts. The atmospheric pressure is falling slightly, which might stir some action. Wildlife watchers score 6.3, a bit lower than previous days, but the solunar periods could still offer some interesting sightings. Compared to recent history, today’s conditions are consistent with the past week, though slightly more gusty than yesterday, which saw a bit calmer wind at 11.6 knots. The sea surface temperature is a comfortable 26.7°C, slightly warmer than average, perfect for a dip. Looking ahead, expect a slight increase in wave activity over the next few days, with winds peaking at 15.3 knots by September 3rd. Rain chances fluctuate, so keep an eye on the skies. For those seeking the best bet, hoist your sails and enjoy the afternoon breeze—it’s a sailor’s paradise out there today!
