Oahu Surf Zone Forecast FZHW52 PHFO 130106 SRFHFO Surf Zone Forecast for Hawaii National Weather Service Honolulu HI 306 PM HST Sun Apr 12 2026 .DISCUSSION... A moderate, medium-period north-northwest swell (340 degrees) generated by the formerly-gale force low north-northwest of the main Hawaiian islands is filling in along north and west facing shores this afternoon. This swell will maintain small to moderate surf through Monday, followed by a decline in northwest swell energy for the rest of the week. A medium-period south swell will continue to decline through Monday. By Tuesday, however, a new south swell will arrive, once again providing a boost to surf along south facing shores through mid week before gradually subsiding into the weekend. Surf along east facing shores will remain below seasonal average with lighter than average trade winds near and upstream of the islands forecast through 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.
