Swell Summary
Well-developed trade wind swell will maintain rough east shore surf above seasonal average tonight. East shore surf will steadily decline Wednesday and Thursday, then fade on Friday and the weekend. Surf along south facing shores will remain small through the week.
Swells from the north-northeast and the northwest are due Thursday into early next week, with swells from both directions peaking on Sunday. A moderate medium period north-northeast swell will build on Thursday and persist through early next week. A tiny northwest swell is due on Thursday through Friday. This will be followed by a moderate medium period northwest swell Saturday night and Sunday, and a smaller reinforcing pulse of swell is due Monday and Tuesday. None of these swells is expected to produce advisory level surf on north, west, or east shores.
