Swell Summary
A small size, short to medium period north northwest is expected fill in late tonight into Tuesday. Another small northwest to north northwest bump is expected over the weekend.
A series of small long-period south-southwest swells will provide surf near the summer average along south facing shores throughout the week. Strengthening trades later this week will bring an increase of short-period energy and will bring elevated surf along east facing shores by Thursday or Friday.
