Honolulu Harbor, HI Daily Water Report — September 1, 2026

Today is shaping up to be an exceptional day for surfing and sailing at Honolulu Harbor, with both scoring high marks in suitability. Surfing gets a stellar 9.4 out of 10, thanks to wave heights around 1.26 meters with a solid period of 9.9 seconds. Winds from the northeast at 10 knots, gusting up to 25, will keep things lively but manageable for experienced surfers. Sailors will also find favorable conditions with a suitability score of 9/10, aided by consistent wind and moderate cloud cover. Divers can rejoice with an 8.7/10 score, indicating excellent underwater conditions. The sea surface temperature is a comfortable 26.7°C, and the water remains oligotrophic, suggesting clear blue waters with low productivity. This clarity, combined with manageable wave activity, promises a great day beneath the surface. On the flip side, kayakers might want to reconsider their plans today. With a low score of 3.6/10, the combination of wind and wave conditions could make for a challenging paddle. Boaters, too, should exercise caution, as their score sits at 5.7/10, reflecting similar concerns with wind gusts and wave heights. Fishing enthusiasts, however, might find the solunar periods promising, with a score of 7.9/10. The major feeding windows in the early morning and afternoon align nicely with the harbor's conditions, though the lack of tide data means anglers will have to rely more on timing and their own intuition. Looking ahead, the next few days will see increasing wave heights, peaking on September 7th with swells reaching up to 2.2 meters. So, if you're planning to hit the water, today might just be your best bet for a balanced mix of excitement and safety.
