October 13, 2018 Surf Forecast
Swell Summary
Outlook through Saturday October 20: Small reinforcing swells out of the north and south expected over the weekend and early next week will support small to moderate surf continuing along exposed shores. A large northwest swell is expected Tuesday through midweek, that will likely generate advisory-level surf along north and west facing shores late Tuesday through Wednesday. This source will slowly ease through the second half of the week. Another small to moderate south swell is expected late next week. Surf along east facing shores will remain small.
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.
