Background info: This upcoming fall I will be in South San Diego area for college. I was wondering what types of crowds to expect. Can you find spots were no one is out but still good waves? How crowded do known spots get (Blacks, Swamis)? At what sizes do the crowds thin out? (either due being large or small) Is it worth going up or down the coast (into Baja) to find uncrowded surf? Are crowds aggressive or are they relatively passive? How are the lifeguards? Designated Surf zones?
