.DISCUSSION...
The current long-period south swell will continue to build today,
then peak near the advisory level tonight into early Wednesday. A
High Surf Advisory will likely be required as the swell peaks.
This swell with then slowly fade during the middle of the week,
but will be followed by a new long-period south swell arriving on
Thursday, which will keep surf elevated above the summertime
average through the weekend.
Surf along east facing shores will remain slightly below seasonal
levels today through Wednesday as the trades ease upstream of the
islands. East shore surf should then build back close to seasonal
levels late this week and through the weekend as stronger trades
return over and upstream on the islands. Additionally, swell
generated by former tropical cyclone Elida may give a slight boost
to east shore surf during the middle of the week.
Surf along north-facing shores will remain at flat to tiny levels
through the weekend.

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.
