921 FZHW52 PHFO 201315 SRFHFO Surf Zone Forecast for Hawaii National Weather Service Honolulu HI 315 AM HST Mon May 20 2024 .DISCUSSION... Surf along south-facing shores will remain at or near advisory heights through early afternoon. Recent south shore buoy observations of around 3 to 4 feet, near 16-18 second swell, along with spectral density plots showing additional long period energy reaching southern shores this morning, will maintain High Surf Advisory (HSA) level surf through the early afternoon hours. While south energy will be fading through the day, the HSA has been extended through the afternoon to account for the passage of the tail end of this energy. As the south swell fades, south shore surf is forecast to wane from tonight through the middle of the week. The weekend`s small northwest swell will subside through the day with resultant north shore surf falling to near flat from Tuesday into the weekend. East chop will remain steady through early week. There may be a slight mid to late week uptick in wind wave action as trades strengthen a bit over and upstream of the islands.

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.
