Outlook through Saturday March 17: The current north-northeast swell will continue to subside this weekend. A large and rough north swell will build late Sunday and peak Monday, with surf likely reaching the high surf warning level along north facing shores and topping the advisory level along east facing shores. The short-lived north swell will drop quickly on Tuesday, then fade on Wednesday, but during this time, strengthening trade winds will lead to rough, advisory level surf along east facing shores. Very small north swells and decreasing trade wind swell are expected during the second half of the week 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.
