Open-ocean vs. the face: the heights on buoys and forecast models are significant wave height (Hs) in deep water. What you ride is the breaking face, which depends on period, direction and this break's bathymetry — that's why the two rows above differ. PierMonkey's spot ratings already do this conversion for you.
The window runs south through west-northwest, with a major island caveat: south-southeast to southwest energy wraps in and lights the north side (the summer engine), while west-northwest winter energy that clears the islands, plus long-period northwest refracting through the Catalina–Palos Verdes gap, feeds the south side. As the swell angle rotates west of about 210°, Catalina shadows Huntington — the north half first, then the whole beach by around 215–220°.
Period matters more than raw height: 14-to-18-second groundswell punches through and jumps in size on the banks. On a clean, on-angle long-period day the face runs a bit larger than the buoy height; on a shadowed southwest day it runs smaller.
