.DISCUSSION...Two moderate, long-period NW and NNW swells moving through
the waters will maintain elevated surf along N and W facing shores
through Saturday and then trend down on Sunday. A hurricane force low
E of Japan will bring another round of moderate, long- period NW (330
deg) swell into the islands towards the middle of next week leading to
building surf along N and W facing shores. This next long-period
swell may reach low-end High Surf Advisory thresholds Wednesday into
Thursday.
A series of small, medium-to long-period S to SW swells will
filter into the area through the weekend keeping surf along S
facing shores from going flat. Short-period surf along E facing
shores increases slightly on Saturday due to the stronger trades,
then trends down slightly Sunday through early next week.

Surf: Height of the surf from trough to crest (face value)
in feet.
Tides: Heights displayed are relative to the Mean Lower Low

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.
