Swell Summary
Surf along exposed north facing shores will steadily lower through Sunday as a north swell eases. Another north-northwest swell will build in from Sunday night into Monday, then linger through a good portion of next week. Surf heights along both west and north facing shores are forecast to peak near or slightly below the advisory thresholds early next week.
Surf heights along south facing shores will diminish to background levels today and then rise again early next week as overlapping long period south swell energy moves into the Hawaii Region. Surf heights along east facing shores will remain small through much of next week due to lighter winds forecast across the state.
