Honolulu Harbor, HI Daily Water Report — September 2, 2026

Today is a prime day for surfers and sailors at Honolulu Harbor, with both activities scoring an impressive 9.2 out of 10. The steady ENE winds, peaking at 13 knots and gusting up to 31.5 knots, provide excellent conditions for catching waves and harnessing the wind. The swell, coming from the south at 1.04 meters with a 12.75-second period, complements the wind waves to create ideal surfing conditions. Divers will also find today quite favorable with a score of 8.5, although slightly down from yesterday's 8.7. The water temperature remains inviting at 26.7°C, and the oligotrophic waters suggest decent clarity below the surface. Boaters and kayakers, however, might want to exercise caution. Boating scores a middling 5, while kayaking is less favorable at 3.2. The combination of wind gusts and a 1.44-meter wave height might make for a choppy ride, with the current pushing westward at 1.3 m/s. If you do venture out, early morning offers the calmest waters, with waves at their lowest around 1.28 meters near 1:00 AM. Fishing enthusiasts might find today less rewarding than earlier in the week, with a score of 5.9. The solunar major period in the afternoon could be your best bet, but variable tides and rising barometric pressure might pose challenges. Wildlife watchers can expect moderate activity, scoring 5.6, as the wind and tide conditions aren't particularly conducive to sightings. Looking ahead, the next few days bring a mix of conditions. Winds remain brisk but start to ease after the weekend, and wave heights will increase significantly by the 7th and 8th, providing even more excitement for surfers. If you're planning an outing, consider catching the waves or wind today, as it's one of the better days for those water activities this week.
