Honolulu, HI Daily Water Report — October 8, 2026

Honolulu’s water day is a qualified go: diving is the standout at 8.6/10, sailing is workable at 7/10, but paddlers and small-boat crews should treat the building evening wind and persistent rain as the price of admission. This is not a flat, glassy day; it is a warm-water, moving-water day with enough swell and chop to reward good timing. The best all-round daylight window is late morning through early afternoon, roughly around the 10:01 AM–12:01 PM solunar major period and the 2:30 PM high tide. Winds are lighter earlier in the day before the stronger gust potential develops, while the 0.96 m south swell at 11.45 seconds keeps some organized energy in the water. Total waves run 1.1–1.8 m, with a representative 1.38 m, plus short-period wind waves around 0.66 m. That combination is manageable for capable crews but can turn a simple outing into a wet, bouncy one when the breeze fills in. Diving earns the day’s best score, supported by 27.2 C marine surface water and the available clarity inputs in the model. That score is not a safety clearance: surface conditions, surge, rain, and site-specific entry conditions still matter. Atmospheric visibility is only 2.54 km under full cloud cover and rain is possible throughout the day, so do not confuse the gray sky with an underwater-visibility forecast. Fishing sits at 5.7/10. The late-morning major period is the cleaner timing choice, with another major period from 10:01 PM to midnight for those operating after dark. The pressure is rising from a relatively low 1008 hPa, but wind and rain limit the day’s upside. Wildlife scores 6.8/10, with the 8:26 AM and especially 8:48 PM low tides offering useful timing context; it is not a promise of sightings. Compared with the last several days, wind is notably less forgiving than the light 3.1-knot conditions recorded October 7, and boating and kayaking scores have slipped accordingly. Gusts may reach 27.4 knots near 6 PM, so the late-day return is the part to plan hardest. The outlook improves steadily: waves ease toward 1.0–1.1 m by October 12–14 while forecast peak winds stay mostly below 7 knots. Best bet: dive or sail before the afternoon wind starts throwing its elbows.
