Outlook through Sunday August 12: A series of small south swells are expected through Monday with a slightly larger south swell expected Tuesday and Wednesday. Another small south swell is expected Friday and Saturday. A small north swell is expected to arrive late Tuesday, peak Tuesday night and Wednesday, then lower gradually Thursday and Friday. Short period choppy surf will continue to impact east facing shores. Swells from Hurricane Hector may impact some south and east facing shores during the middle 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.
