Kahului, Kahului Harbor, HI Daily Water Report — October 7, 2026

Kahului Harbor gets a clear green light for boating and kayaking today, with a caveat: it is a gentle-wind day, not a flat-water day. The activity models rate boating 9/10 and kayaking 8.6/10, supported by light south winds around 2 knots, no rain indicated, and a modest 0.8–0.9 m sea. That is workable water, but the 0.8 m south swell at 11.3 seconds still has enough pulse to matter around exposed entrances, shorelines, and any place where the harbor’s shelter runs out. The best all-around window is early, from dawn through the late-morning solunar major period of 9:09–11:09 AM. Winds are light, the morning low tide at 6:05 AM has begun filling, and the noon high of 0.76 m arrives at 12:43 PM. The afternoon is still usable, though the day’s strongest gusts are forecast near 1 PM, reaching 13.2 knots, while the heat climbs toward 32.1 C. Bring water, shade, and a little patience for the warmer part of the day. Fishing earns a middling 5.8/10 rather than a banner-day call. The late-morning major period is the most promising timing cue, with another major period from 9:09–11:09 PM, but the forecast’s stable 1010 hPa pressure and light wind do not turn that into a guarantee. Wildlife scores well at 8/10, particularly around the low-tide windows, but that score is a timing-and-conditions estimate, not a wildlife sighting forecast. Sailing is a modest 6.2/10: smooth air is pleasant for drifting and instruction, less so for anyone hoping to make steady progress under sail. Diving has no valid score today, so conditions should not be treated as a dive recommendation. Atmospheric visibility is excellent near 45 km, but it says nothing about underwater clarity. Compared with the recent record, today is calmer than the windier October 4–5 stretch and close to the low-wind pattern of the past week, though fishing scores lower than yesterday’s reconstructed 6.9/10. Thursday and Friday bring higher rain chances and seas up to 1.3 m; Saturday looks drier with 0.8–0.9 m waves, and the early next week marine trend eases further. Best bet: launch early, work the rising tide through late morning, and be back in before the afternoon heat and gusts get ideas.
