Honolulu Harbor, HI Daily Water Report — August 29, 2026

Honolulu Harbor is serving up a mixed bag today, with conditions favoring surfers and sailors but posing challenges for kayakers and boaters. The surfing scene scores a near-perfect 9 out of 10, thanks to a steady wave height of 1.38 meters and a welcoming swell from the south. Sailors will also find their groove with a robust 9.2 out of 10, aided by consistent ENE winds averaging 11 knots, although gusts peaking at 31 knots this afternoon could test your mettle. Divers won’t be disappointed either, with an 8.6 out of 10 score indicating favorable underwater conditions, despite the lack of tide data. The water temperature is a comfortable 26.9°C, making it a pleasant day for exploring beneath the surface. Fishing enthusiasts will find decent opportunities during the solunar major period from 12:25 to 14:25, with a score of 7.4 out of 10, slightly better than yesterday. Boaters and kayakers, on the other hand, might want to reconsider their plans. With a boating score of 6.2 and a kayaking score of 4, the choppy wind waves and strong currents could make for a less-than-relaxing outing. Compared to recent days, kayaking conditions have been consistently low, so it might be worth waiting for calmer seas. Looking ahead, the next few days will see a slight drop in wave height, with winds remaining steady, although rain chances increase notably on August 31. For the best bet today, grab your board and hit the waves early before the afternoon gusts ramp up; it's a prime day to ride Honolulu Harbor's surf.
