Swell Summary
The current small northwest swell will lower through Thursday. A new long-period south swell will slowly fill in today, peak tonight through early Thursday, then lower late Thursday through Friday. Surf heights may approach low-end advisory levels during the peak of this swell. A slightly smaller south swell is expected over the weekend. Short-period choppy surf along east facing shores will become rather small over the next several days as trade winds diminish over and upwind of the state.
