Can I even hike peaks right now?

Hello hello! Question I've been wondering for awhile: While I assume that different peaks in socal have different climates because of altitude differences, are there places around LA that are generally okay to climb in October? I've been particularly wondering about Mt. Wilson or Mt. Baldy, but I'm kind of assuming that Mt. Baldy might be a no-go at this point. Assuming that these are definitely not doable until spring/summer, where you would go to do some similar training? (Silly question I know, I'm semi-new down here and am still getting the lay of the land.)
