Kahului, Kahului Harbor, HI Daily Water Report — October 6, 2026

Kahului Harbor gets a firm go for boating, paddling, and diving today, with the caveat that the calm-looking morning should not be mistaken for an all-day free pass. Boating leads the board at 8.7/10, kayaking follows at 8.1, and diving is the standout at 9.2. A modest, steady 0.8 m sea and light representative ENE wind near 3 knots set up a notably workable water day, while the 26.8 C marine temperature keeps immersion comfortable. The best all-around window is early, from dawn through late morning. Wind is at its lightest around the day’s calmest sea state near midnight and remains generally manageable into the morning; sunrise is 6:19 AM. The rising tide from the 5:13 AM low of 0.12 m toward the 12:15 PM high of 0.78 m also gives shoreline explorers more water to work with as the morning develops. Anglers have their strongest score of the day at 6.9/10, with the 8:21–10:21 AM solunar major period the cleanest timing play. The afternoon minor period, 2:51–3:51 PM, is worth noting, but it overlaps the less settled part of the day. That tradeoff is gust potential. Although the representative wind is gentle, gusts are forecast to reach 22.2 knots around 2 PM, with rain possible from 1–5 PM. The swell is 0.76 m at 12.9 seconds from 189 degrees, so it has enough period to deserve attention even without a large headline height. Current is about 0.22 m/s toward the southeast. Conditions may be excellent for diving by the supplied score, but that is not a safety declaration; assess the actual entry, exit, and surface conditions before committing. The reported 23.56 km atmospheric visibility is encouraging for travel, not a measure of underwater visibility. Compared with the recent reconstructed score history, today keeps the strong diving and boating pattern intact, while sailing slips to 6.1 as the wide gust spread makes steady wind harder to count on. Kayaking improves sharply from yesterday’s 6.4, though the afternoon still has teeth. Wednesday stays light-wind with 0.8–0.9 m waves, while Thursday looks wetter and bumpier, up to 1.2 m. Best bet: launch early, use the rising-morning tide, and be back in before the afternoon gusts decide to audition.
