The viz can be poor in the LA basin in Nov. It can be really poor (2-3 mi) near downtown LA.
E of, say, Palm Springs the viz is usually unlimited but even there winter storms can sweep down from the NW with strong winds. Better weather earlier in the month.
On the plus side, temps are cooler and the ride smoother at this time of year, so you can to lots of 'hot n' high' places!
