Swell Summary
Surf along north facing shores will continue to decline as the short to medium-period north swell fades through the end of the week. Surf along east facing shores will remain tiny except shores exposed to the north swell this evening. The return of fresh to strong trades will allow for rough and choppy surf to gradually build back to near normal levels Friday through the weekend.
A mix of background southwest and southeast swells will produce small surf over the next few days. A slight uptick is expected from the south south-west this Friday as a small long period swell moves in and holds through the weekend.
