December trip

is it possible to go to a sandbar in December or is it too cold?

Visiting a sandbar in Key West during December is definitely possible, but there are a few things to consider regarding weather and water conditions. December in Key West is part of the dry season, so rainfall is low, but temperatures are cooler than the summer months.

Average temperatures in December typically range from the mid-60s to mid-70s °F (18–24°C), with water temperatures around 72–76°F (22–24°C). While the air is pleasant, the water may feel cooler for prolonged swimming, especially for children or those sensitive to cooler temperatures.

Some key points for planning a sandbar visit in December:

  • Choose a sunny day to maximize warmth, as cooler air temperatures can make time on the sandbar feel chilly.
  • Consider bringing a light wetsuit or rash guard if you plan to swim for extended periods, particularly for teens or kids.
  • Boat tours or private charters can still access popular sandbars like Sand Key or shallow areas around the Marquesas Keys, but confirm with the operator about water depth and conditions in December.
  • Check the weather forecast for wind and wave conditions, as stronger winds can make the sandbars less comfortable and the water choppier.

Overall, a December trip to a sandbar in Key West is feasible and enjoyable for a short visit or light swimming, but be prepared for slightly cooler water and air temperatures than summer months. Layered clothing and quick-dry options can help maximize comfort.
