A large, medium period north (340 to 360 degrees) swell will continue to gradually decline over the next couple of days as it shifts out of the north-northeast (360 to 020 degrees). Surf heights this morning will be just under the High Surf Advisory criteria and slowly decline through the day.

A moderate, long period northwest swell will begin to fill in late tonight and hold through Wednesday. Guidance hints for reinforcements of similar size to hold through the week from the northwest.
