Swell Summary
A small, short period NE and a small, medium period NW swell will continue to slowly decline into Tuesday. A pair of overlapping small to moderate, long period NNW (310-340 degree) swells will arrive Tuesday, peaking Wednesday. Surf could peak near or above High Surf Advisory (HSA) thresholds along exposed N and W facing shores before gradually declining Wednesday night through the end of the week. Another overlapping small, short to medium period N (350-010 degree) swell arrives Thursday into Friday. Then another moderate, long period NW (310-330 degree) swell arrives Friday, peaking near HSA thresholds over the weekend.
Surf along E facing shores will continue to decline tonight into Tuesday due to the weakening of the local and upstream trade winds. As a new high pressure builds N of the state Wednesday through Thursday, rough and choppy surf along E shores could near HSA levels. For S shores, periods of tiny background south swell energy will continue to move through keeping surf from going flat.
