I haven't been to Southern California, nor have I been studying surf reports from magicseaweed or elsewhere, but just from watching many videos of trestles and reading the erBB community surf report I get the impression it's not a windy place and gets a lot of clean conditions. Gets some sort of wave most days, a lot of small wave days. Am I close?
Vic Au is quite different. Windy with weather patterns which last several days in a row rather than some morning or evening glass off. For example several days in a row of offshore, then several days in a row of onshore winds would be typical. We have a lot of high cliffs which mean that a very strong offshore can be fine to surf in.
