Outlook through Sunday May 20: The latest in a series of small north-northwest swells is due Monday and expected to fade by Wednesday. Two more pulses of small to low-end moderate north-northwest swell are forecast Thursday through next weekend. A moderate south swell is expected to arrive tonight, gradually build through Tuesday, then slowly subside Wednesday and Thursday. Another moderate south swell is due next weekend.
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.
