How cold does it generally get at the beginning of december? I'm flying out and will be in san fran from the 5th-9th.
Going to try to go with just a backpack since bags coast extra + I don't want to lug around a bag once I check out of the hotel on the 9th and wander around the city till my flight leaves.
Also it just occurred to me that maybe I don't want to wonder around with nowhere that's warm till the late evening. Almost booked a flight out at 11:30 pm to maximize my time out there without having to get another hotel but then realized it might be fucking cold.
