HIGH SURF ADVISORY FOR SOUTH FACING SHORES

Swell Summary

A long-period south-southwest (200 degrees) swell moving through will continue to generate advisory-level surf today, which could persist into the overnight hours tonight. A downward trend is expected Tuesday through midweek as the swell begins to ease. A similar long-period south swell is expected to arrive Thursday night into Friday, then peak late Friday into Saturday. Surf along north-facing shores will remain up slightly through the first half of the week as small north to north-northwest pulses move through. A return of summertime conditions is expected along north facing shores later in the week. Surf along east facing shores will trend later in the week as the trades become established locally and upstream across the eastern Pacific.
