What December feels like
December brings the coldest nights of the year, and away from the waterfront they surprise people every winter — frost on the windshields out toward the airport is normal. The harbor parade of lights is the local December event, weather permitting.
Expect about 4 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy.
Can you swim?
The ocean runs about 60° — cold — a quick dip takes resolve.
