Nawiliwili, HI Daily Water Report — October 8, 2026

Nawiliwili is a good-but-not-carefree water day: diving leads the board at 8.8/10, while boating and kayaking remain workable at 6.8 and 6.3. The catch is simple—light winds do not erase a 1.2–1.4 m sea. The most useful window is early, around and after sunrise, before the forecast rain window finishes and well ahead of the 2 PM gust peak. Winds are generally light, but gusts could reach 18.5 knots around 2 PM, enough to make an otherwise modest 4-knot NNE day feel less settled on exposed water. The calmest wave height is forecast near midnight at 1.2 m; through daylight, the representative sea is 1.26 m at 11.15 seconds, driven largely by a 0.82 m south swell. That is not huge water, but it is real moving water, particularly for small craft and anyone planning a long paddle. Diving gets the strongest nod thanks to warm 26.6 C marine water, light average wind, and the available clarity inputs used by the score. Still, the weather forecast calls for rain through 1 PM, with 2.88 km atmospheric visibility and very humid air; neither number is a promise of underwater visibility. Boaters should also keep the rising pressure in perspective: it is climbing from a low 1007 hPa representative reading, but rain, cloud, swell, and afternoon gusts remain the operational tradeoff. For fishing, the 5.7/10 score is middling rather than magic. The late-morning solunar major period, 10:06 AM to 12:06 PM, is the cleanest timing cue, arriving as the tide rises from the 8:00 AM low toward the 2:14 PM high. A second major period runs 10:06 PM to midnight. The 7% waning crescent provides little moonlight after dark. Compared with yesterday, boating, sailing, kayaking, and wildlife scores have all eased, while fishing is nearly unchanged. The next several days retain light peak winds, but seas stay around 1.3–1.5 m through Sunday before gradually easing toward 1.2 m by next Wednesday. Best bet: make an early, conservatively planned dive or short boat outing, then let the afternoon gusts have the last word.
