Swell Summary

Surf along exposed north and west facing will peak tonight as a north-northwest swell creates advisory level surf for north facing shores. Surf will ease Wednesday morning into the second half of the week as the swell shifts out of the north-northeast and becomes shorter period. A new northwest swell is expected to arrive Friday night into this weekend and provide fresh medium- to long- period swell energy.

Surf along south shores will also trend up through midweek as a fresh long period south swell arrives. This swell will peak Wednesday through Thursday, then ease into the weekend. Surf along east facing shores will remain well below average due to the lack of trades locally and upstream. The exception will be for east facing shores exposed to north-northeast swells expected later this week.
