Surf Zone Forecast for Hawaii
National Weather Service Honolulu HI
357 AM HST Thu Jul 31 2025

.DISCUSSION...A moderate to large long period south (190 degrees) swell
will build to near warning levels this afternoon and is expected to
hold through Friday, then gradually decline through the weekend.

East shore surf will remain elevated and choppy due to locally
strong trade winds through this weekend. This will be followed by
a decline early next week as trades weaken.

Flat summer conditions along north facing shores may be
interrupted late this weekend by a small long period northwest
swell from Typhoon Krosa, currently in the western Pacific.

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.
