Swell Summary
South shore surf will be on the rise today with the arrival of an anticipated large, long period south swell. Offshore southern buoys are showing the high period frontrunners while the nearshore PacIOOS Barber's Point buoy is registering rising swell within the higher energy bands. Several pulses within this swell will have this south shore surf event lasting through mid week. A High Surf Advisory will likely be in effect for south facing shores as early as this afternoon but certainly for peaking surf at or slightly above 10 feet Tuesday and Wednesday.
The ongoing fairly low, moderate period northwest-west swell will be slowly declining through Tuesday. This will have north and west facing shore surf gradually falling through late Tuesday.
Surf along east facing shores will remain relatively small the next several days. Swell within the captured fetch from Hurricane Linda in the East Pacific might make it to the east facing shores of the eastern most islands as small, long period east swell by Wednesday.
