Pearl Harbor, HI Daily Water Report — October 8, 2026

Pearl Harbor is a qualified go, with diving the clear standout and everything else requiring a little more patience than the recent run of easier water. The day carries a 1.2–1.8 m sea state, with a representative 1.48 m at 9.7 seconds, plus short 0.78 m wind waves. That is enough motion to make small-craft plans less casual, especially as southerly winds build from light early values toward a 25.1-knot strongest gust around 3 PM. For divers, the 8.5/10 score leads the board: warm water near 27.1–27.6 C and a longer-period 0.96 m south swell provide the better side of the equation, though surface conditions and rain are the tradeoff. Atmospheric visibility is only 1.32 km under overcast, rainy conditions; that is a navigation and weather consideration, not an underwater-visibility reading. Boating and sailing both sit at 5.8/10, while kayaking is 5/10, reflecting the wave, current and precipitation mix rather than a green light for carefree outings. The current is forecast at about 0.39 m/s toward 23 degrees, another detail worth respecting when choosing timing and route. The most workable general window is early, before the afternoon gust peak, with the first low tide at 8:30 AM and a midday solunar major period from 10:01 AM to noon. Fishing rates a middling 5.7/10; the solunar timing and rising pressure help, but wet weather and increasing wind keep it from being a banner call. A second high tide arrives at 2:45 PM, followed by the 4:31–5:31 PM minor solunar period, but that overlaps the rougher, gustier part of the day. Wildlife scores 6.8/10, unchanged from yesterday’s reconstructed rating. Compared with the previous two days, conditions are notably less friendly for boating and paddling: yesterday’s boating score was 7.4 and kayaking 7.5, while diving improves from 7/10 yesterday but remains below the 8.8 recorded Tuesday. The sea is warmer than the supplied average by 0.4 C. Friday and Saturday keep rain chances high, with waves around 1.3–1.7 m; a steadier easing trend appears Sunday into next week as waves settle toward 1.1–1.3 m and winds stay light. Best bet: dive early if your operator is comfortable with the conditions, and let the afternoon gusts have the last word.
