May 09, 2018 Surf Forecast
Outlook through Tuesday May 15: A reinforcing north swell will slowly decline through Wednesday. Surf along east facing shores will be a couple of feet higher from yesterday, brought on by the strengthening trade winds. This short period, locally-generated swell will drop off on Wednesday night as the trades weaken. South facing shores will continue to have small surf through the forecast period.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
