Honolulu Harbor, HI Daily Water Report — August 23, 2026

Today is shaping up to be a stellar day for surfers and sailors around Honolulu Harbor, with both activities scoring a remarkable 9.2 out of 10. The combination of steady northeast winds at 12 knots, gusting up to 27 knots, and a wave height of 1.46 meters with a decent period of 8.45 seconds, provides ideal conditions for catching some waves or setting sail. The swell coming from 184 degrees, at 0.72 meters and 12.55 seconds, adds a nice touch for those looking to ride the ocean's rhythm. Divers will also find today quite appealing, with an 8.6 out of 10 score. The oligotrophic waters, with low chlorophyll levels at 0.07 mg/m3, promise clear blue visibility beneath the surface. Surface sea temperatures are a comfortable 27°C, making it an inviting day to explore underwater. Fishing enthusiasts have a decent window with a score of 7.2, particularly during the solunar major periods from 5:46 to 7:46 AM and 5:46 to 7:46 PM. However, the low tide at 6:09 AM might require a bit of patience. Wildlife watchers can enjoy a good day as well, scoring 8.1, especially around low tide when marine life is more visible. Boating and kayaking, however, aren't as favorable today due to the choppy conditions created by wind waves of 0.9 meters and an ocean current of 1.5 m/s. These conditions yield lower scores of 4.8 and 3.2, respectively, suggesting some caution is warranted. Looking ahead, conditions remain relatively stable with slight chances of rain increasing midweek but winds easing slightly. For those seeking the perfect wave or sail, today is your best bet.
