March 12, 2018 Surf Forecast
Outlook through Sunday March 18: A large, short period north swell will build tonight and peak Monday, with surf potentially 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 Tuesday, then fade Wednesday, but during this time, strengthening trade winds will lead to rough, advisory level surf along east facing shores. Small north swells and a 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.
