Swell Summary
Small surf is expected along north and west facing shores through the remainder of this weekend. A moderate, medium period northwest (310-330) swell is due to enter the local waters on Monday. This swell will push surf to near the April average, followed by a decline Tuesday and Wednesday. A slightly larger north northwest (330-350) swell is progged to arrive Thursday and could produce surf that approaches advisory levels through at least Friday.
Elevated rough surf will continue along east facing shores through Monday, due to the breezy trades. Surf should then subside Tuesday into mid- week as winds ease locally and upstream of the state.
Surf along south facing shores will remain near or below April average as typical background south swell moves through, keeping surf from going flat through much of next week.
