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.

Product Legend:

Surf:        Height of the surf from trough to crest (face value)
             in feet.

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.
