Swell Summary
Surf along exposed north and west-facing shores will climb well above average for this time of year on Saturday as a fresh, medium-period north-northwest (330-340 degrees) swell arrives. This north- northwest source should peak on Saturday then steadily decline Saturday night through early next week.
Surf along exposed south-facing shores will continue to see a mix of long-period background south-southwest and shorter- period southeast swell through the middle of next week. A larger long- period south-southwest swell is possible late next week and could produce above average surf by next weekend.
Surf along east-facing shores will gradually build over the weekend and into early next week as breezy to strong trade winds return upstream of the state.
