Swell Summary

A mix of short period NNW swell which peaked at the outer buoys early this morning, and declining mid- long period swell (12 to 16 seconds) will keep small surf in place through tomorrow. Both of these swells drop off by Monday, allowing surf to drop to tiny levels through much of the week before a small northwest arrives towards the end of the week.

A mid to long period south-southwest swell (15 seconds) will keep above average surf in place tonight over south shores, then decline tomorrow and remain small through much of the week with background south swells. A small long period swell is possible next weekend.

Rough trade wind swell will produce above average surf for E shores through Tuesday before declining with weakening trades mid- week. Expect some wrap of NNW swell for exposed shorelines through tonight.
