Wetsuits &
Water Temps

The swim should be wetsuit legal (below 78 degrees), as it has been in all previous years. The average Key West water temperature in December is 72 degrees which is perfect for swimming either with or without a wetsuit.  A wetsuit will make you more buoyant (safer) and will most likely decrease your swim time.

78 degrees or less: WETSUIT LEGAL

Average water temp: 72 degrees
