For protection from the hot sun of Key West, it is always best to cover yourself as much as possible. Caps or sun hats, bandanas, sun glasses, and of course sun screen are all necessities. In the winter, it can be quite cool and breezy offshore, so a light weight jacket may be useful. For winter season early morning trips, a pair of light gloves can also add comfort. Bring a small day pack or duffel bag for your extra clothing, cameras, binoculars, and other necessities.
