Swell Summary
Surf is expected to remain below advisory levels on all shores over the next week. The current short-period north (350-010 degree) swell will continue to decline today. A mix of small northwest swells will maintain modest surf along many exposed north and west facing shorelines Wednesday into Friday. Increased easterly winds around midweek will result in choppy wind waves along east facing shores. A small, medium-period south (190 degrees) swell today will help to boost surf a foot or so along many south facing shores into Thursday morning.
