Oahu Surf Zone Forecast FZHW52 PHFO 020201 SRFHFO Surf Zone Forecast for Hawaii National Weather Service Honolulu HI 401 PM HST Tue Sep 1 2026 .DISCUSSION... A moderate, long-period south swell will continue to fill in overnight and peak Wednesday. Surf along south facing shores should peak below advisory thresholds. This swell will then gradually decline through the rest of the week. A small, medium- period south southeast swell from Lowell has started to fill and should peak late Wednesday before becoming more southerly Thursday through Friday. These combined swells will keep south shore surf elevated near to just below advisory levels. Beyond that point, the surf forecast is highly dependent on the eventual track and intensity of Lowell, which has the potential to be a significant source of south to southwesterly swell through this weekend and into next week depending on how sharply and quickly the cyclone turns to the north. Trade wind swell energy will maintain rough and choppy surf along all east- facing shores through the coming week. Tonight, a small, medium- period east swell arrives from Hurricane Karina that will build through the week and could push east shore surf to advisory thresholds by this weekend and into next week.

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.
