November is one of those weird months for us. Some days it can be downright toasty in the afternoons. Other days, it can be nicer, cooler weather in the 70's. Generally though, November will see cooler nights. It's best if you bring along a fleece or light jacket to cover your arms after the sun goes down. Get a locker and stash it there until the evening so you don't have to carry it around. It's much better to have one on hand then end up being chilly and buying one!
It'll be a mix though. Best to check the forecast close to when you leave to see how warm it might be or if there's a cold front coming through to make it cooler.
