Swell Summary

Outlook through Monday October 08: A long-period northwest swell arriving tonight is expected to cause surf to approach the High Surf Advisory criteria along north facing shores Tuesday. This swell will gradually diminish Wednesday. A south- southwest swell filling in Tuesday is expected to produce moderate surf along south facing shores Wednesday. A small long- period east swell generated by distant Hurricane Rosa may produce a slight bump in surf heights along east facing shores starting Tuesday. Later in the week, swells from Hurricane Walaka, which is now a major hurricane may produce significant southwest and west swells that may affect south and west facing shores starting Thursday.
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.
