Swell Summary

The anticipated large, long period south swell has arrived and will produce High Surf Advisory (HSA) surf (peaking 10 foot or greater faces) along south facing shores through Wednesday. Offshore southern buoys are verifying this high south swell arrival, 6 to 7 foot swells within the 17-19 second spectral bands. The nearshore PacIOOS Barber's Point buoy is observing consistent 3 foot or greater swell heights within the high 18-22 second spectral bands. The HSA will be in effect through Wednesday afternoon as the enhanced southern swell energy drives this high south shore surf event through mid week.

The fairly low, moderate period northwest to west swell will be slowly declining through Tuesday. This will have north and west facing shore surf gradually falling through the day. Surf along east facing shores will remain small the next several days. Swell within the small captured fetch from Hurricane Linda in the East Pacific might reach the east facing shores of the eastern most islands late this week as small, moderate period east swell.
