Swell Summary
South shore surf will increase from background levels to around summertime average during the weekend. The south swell will slowly build late today, peak Saturday into Sunday, and decline early next week. East shore surf will be near or slightly above summertime average through the weekend, then build, as trade winds are expected to increase over and upwind of the islands early next week. Aside from some localized wrap of trade wind energy, surf along most north facing shores will remain nearly flat into next week.
