Swell Summary
An extra-large northwest swell will be slow to diminish today, then shift to the north tonight and Friday as it gradually eases. Another powerful, but smaller, very long-period northwest swell is expected Saturday through Monday, with peak surf heights approaching High Surf Warning values. After this long-lived swell eases, surf heights early next week look to remain below Advisory levels along all shores as moderate-sized northwest swells arrive. A tiny south swell is possible this weekend.
