HIGH SURF ADVISORY FOR SOUTH FACING SHORES

Swell Summary

The current High Surf Advisory for south facing shores has been extended through Monday afternoon. Although the current south- southwest swell has declined slightly from its peak and surf may come down just below advisory levels today, a bigger moderate long period south- southwest swell is expected to slowly fill in this afternoon as long period forerunners arrive, then peak Sunday night into Monday.

A tiny pulse from the northwest will give a slight bump for north facing shores. Wind waves for east facing shores have diminished significantly and will remain small today before ramping back up as wind wave chop increases due to the trade winds.
