What January feels like
January is the island at full occupancy — Duval is loud and the sunset crowd at Mallory Square starts gathering absurdly early. When a front swings through, the wind comes hard out of the north and the snorkel and ferry boats begin cancelling.
Expect about 3 days with real rain — enough to notice, not enough to plan around. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 72° — comfortable for swimming.
