What December feels like
December here is a coin flip: some winters bring a proper snow before Christmas and some bring weeks of cold grey drizzle instead. The National Christmas Tree draws crowds through mid-month, then the city empties out between the holidays and the museums go quiet again.
Expect about 6 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy. about 13 nights dip below freezing.
