Honestly, hard to say. They had a really nice streak of warm and beautiful weather this past November. But, for Thanksgiving 2019, it was cold, windy, rainy and miserable.
More often than not, it's California so you'll have pleasant California weather. But, sometimes that California weather likes to throw not-fun surprises at you. (I would also say it depends on your tolerance for cold. I'm from the desert so I don't tolerate it all that well. But if you're from a cold climate, going to the beach on an average November day would probably be fine.)
