Honolulu Harbor, HI Daily Water Report — August 28, 2026

If you're looking to catch a wave or set sail in Honolulu Harbor today, you're in luck. Surfing and sailing are both scoring high, with surfing at an impressive 9.1/10 and sailing close behind at 8.6/10. The combination of solid wave heights around 1.34 meters and a consistent swell from the south make it a prime day for surfers. Sailors will appreciate the steady northeast winds at 10 knots, though gusts up to 27.8 knots could add some excitement to your voyage. Fishing holds steady with a 7.2/10 score, slightly better than yesterday. The solunar periods around midday might offer the best chance for a good catch, so plan your lines accordingly. Diving conditions are also excellent, maintaining a solid 8.6/10. The water temperature is a comfortable 26.9°C, and the clear blue waters promise a rewarding underwater experience. However, boating and kayaking enthusiasts might want to exercise caution. The boating score has dipped to 5.7/10, and kayaking lags at 3.8/10 due to those gusty winds and moderate wave heights. If you do venture out, aim for the calmer conditions expected around 10 PM when wave heights will slightly ease. Looking ahead, the weather is expected to remain fairly stable with temperatures hovering between 22.9°C and 29.4°C over the next few days. However, keep an eye on the sky, as there's a significant chance of rain starting tomorrow, peaking at a 72% probability. For the best bet of the day, grab your surfboard and hit the harbor waves—conditions are just right for riding those southern swells.
