A south swell will fill in early Friday and surf will reach near advisory levels by Saturday. Surf along east-facing shores will maintain over the next several days as the east swell from Norbert declines, but it replaced by chop from the building trade winds. Flat to tiny surf along north facing shores is expected through the forecast period.
