Swell Summary
As the high far northeast of the area continues to move away and with trades weakening, surf along east facing shores is on a gradual decline. However, a new northwest swell is expected to begin arriving later today, and will boost surf along north and west facing shores, with surf nearing advisory levels during the peak of the event Wednesday night through Thursday. This swell is then expected to decline Friday and Saturday. Some small long period south swells will continue to boost surf along south facing shores through the week. No other significant swells are expected.
