Swell Summary
A moderate, long period, northwest swell is expected to arrive in the islands early Tuesday, and linger into the middle of the week, and slowly subside during the end of the week. This swell will maintain elevated surf near advisory levels along exposed north and west facing shores.
East shore surf will remain small into Tuesday as winds taper off. Surf will increase a little bit as the northeast winds pick up along the front, but mostly impact Kauai and Oahu. There are no noteworthy swells for the next few days for south facing shores.
