Swell Summary

Surf along south-facing shores will gradually decline through Monday as the small, medium-period energy slowly fades. A series of long-period swells are expected during the second half of the week. The first pulse will gradually fill in Tuesday into Wednesday out of the southwest, followed by larger south-southwest swells Friday into the weekend. Surf could get near advisory thresholds over the weekend, but at this time it looks like it would peak just below advisory thresholds.

Surf along east-facing shores should see an increase during the second half of the week as the trades strengthen and the remnants of Norbert moves through the islands. Flat to tiny surf along north facing shores is expected through the forecast period.
