A long-period west-northwest swell is expected to continue filling in and hold into the weekend before fading into next week.
Surf heights along east facing shores will start to increase Friday into the weekend as the trades return and strengthen. We could see advisory level surf by Monday / Tuesday.
Along south facing shores small waves are forecast through the weekend with mainly small background long-period energy expected. A long-period south swell is expected to fill in Wednesday.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
