Oahu Surf Zone Forecast FZHW52 PHFO 311839 SRFHFO Surf Zone Forecast for Hawaii National Weather Service Honolulu HI 839 AM HST Fri Jul 31 2026 .DISCUSSION... Fading S swell will be followed by the occasional small, medium period pulse of energy out of the southerly quadrant during the next several days. This will maintain surf slightly below the seasonal average. Small long period forerunners emanating from Hurricane Genevieve in the East Pac have registered on offshore NDBC buoys with some indication of this energy at the nearshore Hilo CDIP buoy as well. This swell will remain small, on the order of a couple feet, as it peaks today and tonight, then fades heading into early next week. This swell will be mixed with building trade wind swell and wind wave action as strong trades become established. N shores remain tiny to flat as do W facing shores except for locales exposed to medium period S swell.

Tides: Heights displayed are relative to the Mean Lower Low Water (MLLW) datum in feet. Surf heights can vary significantly from beach to beach along a coastline. Surf larger than the upper end of the range provided in the forecast will occur periodically, sometimes up to a few hours apart. Expect to encounter rip currents in or near the surf zone, with rip current strength increasing with surf size. Swimmers are urged to exercise caution at all times and enter the water near a lifeguard.
