Swell Summary
The current south swell will continue to gradually decline through the middle of the week. A small long-period south swell is expected to fill in by Saturday to bring surf heights back up for the weekend, though likely remaining below advisory level. Surf along east facing shores will see a slight uptick through Wednesday, before declining slightly Thursday and Friday. Short period chop increases this weekend again as stronger trades develop. Surf along north facing shores will remain tiny through the forecast period.
