March 16, 2018 Surf Forecast
Outlook through Thursday March 22: The current subsiding north swell will be reinforced by a small moderate northwest swell Saturday for a sub-advisory bump in surf for north and west shores. A short-period swell from the north will spread across the island waters Sunday, peaking on Monday, then declining Tuesday. A moderate northeast swell of mid-range period is forecast to arrive Wednesday and build through Thursday. This swell could result in advisory level surf for the east facing shores.
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.
