A longer period west-northwest swell is expected to build Friday, peaks late Friday night and into Saturday morning up to double overhead at the best breaks.

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.
