Swell Summary
The current south swell will continue to gradually decline today. Background small, long-period south southwest swell should fill in Thursday keeping surf slightly below average. A couple of small, long-period southerly swells is expected to fill by the weekend, keeping surf heights near average into early next week, though likely remaining below advisory level. Surf along east facing shores will see a slight uptick later today through Friday due to a small, medium-period northeast swell. Short-period chop increases this weekend again as stronger trades develop. Surf along north facing shores will remain tiny through the forecast period.
