What December feels like
December here runs on candlelight tours and oyster roasts rather than snow, and there is nothing on the ground to shovel — a hard freeze arrives maybe once a winter and the whole city discusses it for days. The week between the holidays books up earlier than people expect.
Expect about 5 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 57° — frigid — locals in wetsuits only.
