Surf Zone Forecast for Hawaii
National Weather Service Honolulu HI
347 AM HST Sun Aug 17 2025

.DISCUSSION...A 2 to 3 foot, medium period south southwest (180-200)
swell will hold today and generate waist to chest high surf, near
seasonal norms. A series of very similar small, medium period south
swells will pass through the local waters over the next several days.
These swells will help to maintain seasonal surf heights along the
south- facing shores, well below advisory thresholds.

Expect chop along east facing shores to remain elevated today,
then lower tonight into Monday morning as trades weaken slightly.
Fresh trades will once again bring elevated choppy conditions to
east facing shores Monday afternoon through mid- week. Flat to
tiny surf will persist along north facing shores through the
forecast period.

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.
