Kahului, Kahului Harbor, HI Daily Water Report — October 5, 2026

Kahului Harbor gets a qualified green light today: sailing is the standout at 8.8/10 and boating rates a solid 8/10, while anglers have a worthwhile 7.2/10 day if they work the timing rather than expecting a glassy all-day cruise. The catch is the wind. ENE flow runs roughly 7 to 14 knots, with gusts forecast as high as 28.8 knots around noon, so the middle of the day may feel considerably more boisterous than the representative 11-knot reading suggests. The best all-around water window is early, from first light through the morning high tide at 11:42 AM. Waves are modest at about 0.6 to 0.8 meters, with a longer-period 0.48-meter swell from 196 degrees, and the day’s calmest wave height is near 0.62 meters around 1 AM. That is manageable water, not a promise of flat water. The rising tide and the 7:28–9:28 AM solunar major period give fishing the day’s cleanest overlap, while the 11:42 AM high tide arrives before the forecast gust peak gets fully involved. Kayaking is more conditional at 6.4/10. The current forecast is about 0.17 m/s toward 146 degrees, and the increasing wind and noon gust potential make an early, conservative outing the better call. Sailing has enough breeze to earn its strong score, but gust spread matters: rig and route for the stronger puffs, not just the average. No diving score is available today, so there is no basis here to recommend it. The listed 17.1 km visibility is atmospheric visibility, not an underwater-clarity reading. This is a windier setup than the very light conditions reconstructed for October 3, when wind was 2.9 knots and kayaking scored 8.4/10. It is also less windy than October 4’s 18.2-knot reading, though today’s noon gust forecast deserves respect. Pressure is falling from around 1015 hPa, and rain is possible in the broader 2 AM–6 PM window despite zero representative precipitation. Looking ahead, winds ease Tuesday through Thursday, but waves build toward 0.9 meters and rain chances rise sharply, peaking at 92% Wednesday. Best bet: launch early, fish the morning solunar window on the rising tide, and be back in before the noon gusts start acting like they own the harbor.
