CatchWindow fishing intelligence

Waikiki, HI Daily Water Report — October 5, 2026

Waikiki gets a qualified green light today: diving is the standout at 8.8/10, while sailing and boating are solid choices if you respect the gusts. Surfing and kayaking are workable rather than exceptional, with both at 6/10; the ocean is not huge, but it is not perfectly tidy either. The water holds near 1.16 m through the day, built from a 0.76 m south swell at 11.15 seconds plus short 0.54 m wind waves. That combination should keep some texture on the surface despite generally moderate northeast winds of roughly 6 to 11 knots. The catch is the gust potential: a strongest gust near 28 knots is forecast around 11 AM. That makes the early daylight window the cleaner bet for paddlers, small boats, and divers, before the gustier late-morning stretch has a chance to make things unnecessarily sporty. For anglers, the better timing is the 7:34–9:34 AM solunar major period, overlapping the rising tide toward the 12:29 PM high of 0.65 m. Fishing rates 6.7/10, helped by the timing and manageable wind, though falling pressure is a modest tradeoff. The evening low tide arrives at 7:39 PM, close to the 7:34–9:34 PM major period; useful timing, but low water and fading light deserve extra care around the shoreline. Diving remains as highly rated as it was yesterday, with 27.3 C marine SST and low chlorophyll reported offshore. That chlorophyll reading describes low productivity, not underwater visibility; the forecast’s nearly 15 km atmospheric visibility is likewise no promise beneath the surface. Still, the diving score reflects the available marine conditions and is the day’s strongest activity signal. Compared with recent CatchWindow estimates, boating improves from yesterday’s 7.1 to 7.4, kayaking edges up from 5.7 to 6, and surfing rebounds from 4 to 6. Sailing slips slightly from yesterday’s 8, likely feeling the gust spread more than the average wind suggests. The next few days keep waves near 1.1–1.3 m, while rain chances rise from Tuesday through Friday. Best bet: make the morning tide and solunar overlap your water window, then let the late-morning gusts have the last word.
