March 13, 2018 Surf ForecastMarch 13, 2018, 1:00 AM HST (Updated March 13, 2018, 1:00 AM)
Outlook through Monday March 19: A large, short period north swell will peak this evening at warning levels on north and east facing shores, then drop quickly Tuesday and Wednesday. However, 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.
