Swell Summary
The current extra-large, long period west-northwest to northwest (300-320 degree) swell will peak this evening then slowly decline through early next week. The next northwest swell is scheduled to arrive next Tuesday into Wednesday and could bring advisory level surf along north and west facing shores.
The out-of-season south swell should peak tonight then gradually decline this weekend. Surf should return to background levels (nearly flat) by the middle of next week. East-facing shore surf will remain small the next couple of days due to the lack of trades. Rough and choppy surf should return this weekend as breezy trades return.
