Swell Summary
Surf along south facing shores will remain just below seasonal average over the next couple of days as an inconsistent southwest swell moves through. A reinforcing southwest swell is expected late Monday into Wednesday. North shore surf will remain tiny through Monday. A northwest swell will arrive on Tuesday and push surf along north and west facing shores well above seasonal average, though below High Surf Advisory levels, Tuesday night and Wednesday. This swell will decline on Thursday and fade Friday. With trade winds on a decline, east shore surf will be well below seasonal average during the next few days. An increase in trade winds will produce larger east shore surf near seasonal average by Tuesday night or Wednesday.
