Trade winds will continue to generate short-period surf along east facing shores and combine with a mid-period northeast swell through Friday. Solid shot of north-northeast expected this weekend, building Friday night and peaking late Saturday, early Sunday.

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.
