Swell Summary

Surf along the east facing shores will be lowering a little each day for the next couple of days as the trade wind weakens. A series of north-northwest to north swells will arrive this week, with the first of three due in today. This small pulse will be reinforced by a slightly larger north- northwest swell Tuesday night through Wednesday. On Thursday night and Friday, a larger north swell arrives, where surf is likely to reach advisory level for the north facing shores. Surf along the south facing shores will remain small into next week, although a long 14 to 15 second period swell is due in tonight through Wednesday.
