Swell Summary
East-facing shore surf will remain below normal through the weekend due to lighter trades upstream of the state. Short period east wind wave swell generated by the remnants of Fernanda, along with long period east swell generated from Hurricane Hilary currently moving west of the southern tip of Baja California Sur, will likely increase eastern shore surf from Monday night through Wednesday. East-facing shore surf heights are forecast to peak out just below surf advisory thresholds Tuesday night into Wednesday morning as this triple shot of locally-generated trade wind wave swell and swells from both Fernanda and Hilary arrive. South shore surf will remain small through the day with a small, medium period swell arriving early next week.
