Swell Summary

The current small northwest swell will continue a gradual decline through Thursday, followed by a moderate north-northwest swell Friday through the weekend. Surf along north and west facing shores should top out around seasonal average during the peak of the swell Friday afternoon and Saturday, then slowly decline late Saturday and Sunday as the dropping swell shifts more northerly and a smaller overlapping northwest swell arrives. Both swells will fade early next week.

Surf along south facing shores will briefly fall near or just below seasonal average as the current south swell continues a slow decline tonight. A new long-periond south swell will build Thursday and may push south shore surf back above seasonal average through Friday. The swell will slowly decline Saturday through early next week.

Surf along east facing shores will remain small through Thursday and will steadily increase Friday as trade winds strengthen over the region. Rough trade wind swell will produce east shore surf above seasonal average Saturday through early next week.
