Swell Summary

Surf along south-facing shores will remain above average over the next couple of days as a long period south-southwest swell holds relatively steady. This swell will then fade during the middle of the week, but will be followed by another small southerly swell shortly thereafter. West-facing shores will experience a bit of the southerly wrap.

Breezy trade winds will maintain moderate surf along east-facing shores for the next several days. Surf along north-facing shores will remain flat to tiny through Monday, but will see a slight bump Tuesday into Wednesday. Then a small, long-period west-northwest swell will build Friday into next weekend, increasing surf along north- and west-facing shores.
