Waikiki, HI Daily Water Report — October 8, 2026

Waikiki is a qualified go today: diving is the standout at 8.7/10, while surfing, sailing and boating sit in the workable middle ground. The catch is weather. Rain is possible throughout the day, skies are fully clouded, and visibility is only 3.44 km in the air—useful for surface navigation, but not a measure of underwater visibility. The water is warm at 27.2 C, with a 1.32 m sea running on a 10-second period and a longer south swell of 0.96 m at 11.45 seconds. Surfing earns 6/10 under the regional model: there is enough moving water for a session, but the estimate is capped without break-specific orientation, bathymetry or tide response. The day’s wave range is 1.1 to 1.8 m, with the calmest conditions near midnight rather than during the daylight lineup. For divers, the warm water and available clarity inputs support the day’s strongest score, though surface conditions still deserve respect. A 0.6 m short-period wind wave, current around 0.39 m/s toward 50 degrees, rain, and gusts that may reach 31.7 knots around 6 PM argue for an earlier, conservative plan rather than a late-day mission. Boating and sailing both rate 6.3/10, but the broad wind range—roughly 1.7 to 12.5 knots—comes with a substantial gust spread. Kayaking is less inviting at 5.4/10, notably down from 8.2 yesterday, as wind, waves, current and precipitation stack up against small craft. The better daylight window is early through mid-afternoon, before the forecast’s strongest gust potential. The 8:26 AM low gives way to a 2:30 PM high of 0.56 m; the 10 AM–noon solunar major period overlaps that rising tide and is the most useful fishing window, though fishing remains a middling 5.7/10. Pressure is rising from a low 1008 hPa representative reading, but rain and wind limit the upside. Compared with the recent run, diving remains near its steady 8.6–8.8 range, while boating and paddling take a clear step back from yesterday’s lighter-wind scores. Looking ahead, winds ease Friday and remain generally modest through next week; seas gradually settle toward 1.0 m by October 13–14. Best bet: make an early, well-planned dive or water session before the afternoon tide tops out and the gusts start showing their teeth.
