Swell Summary
Surf along north facing shores will continue to decline as a short to medium-period north swell fades through Friday, returning to mostly flat levels over the weekend. Surf along east facing shores will rise to near normal levels Friday through the weekend as trade winds return and strengthen. A mix of background southwest and southeast swells will produce small surf for south facing shores over the next few days. A slight uptick is expected from the south-southwest on Friday as a small long-period swell moves in and holds through the weekend.
