What December feels like
December leans into the cold — the light displays, the boat parade, hot chocolate on St. George Street. A hard front can drop a night to freezing, and the coquina plus the wind off the Matanzas make it feel colder than it has any right to.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 63° — cold — a quick dip takes resolve.
