The expected large, long south swell has arrived and will produce High Surf Advisory (HSA) surf (peaking 10 feet or more) along the south-facing coasts by Wednesday. Southern buoys offshore confirm this high arrival of the south swell, 6 to 7 foot swells within the 17-19 second spectral bands. The offshore PacIOOS Barber’s Point buoy observes constant swell heights of 3 feet or more within the high 18-22 second spectral bands. The HSA will be in effect through Wednesday afternoon as the increased southern swell energy propels this high level surfing event on the south coast until mid-week.

The relatively low, moderate period from northwest to west will slowly recede by Tuesday. This will cause the north and west facing bank surf to gradually subside as the day progresses. Surfing on the east-facing banks will remain small for the next few days. The swell within the small trapped swell of Hurricane Linda in the Eastern Pacific could reach the east-facing shores of the easternmost islands as a small, moderate east swell later this week.
