Skylar, I did the cave tubing in Belize in Feb. Yes the water was cool. But, most of your body is NOT in the water, so you don't really feel cold during the float/ride, and the part that is in water, adjusts quickly. It's actually a ride through a system of caves, and so you have sunlight part of the time. The water felt to me, like the local springs around here you can swim in..high 60s to low 70s. My DH is a BIG sissy when it comes to cold water, and he didn't complain a bit.
