A study performed at the University of Florida showed slightly more calories are burned in cold water exercise than in warm. In the study, men who exercised for 45 minutes in 68 degree water burned an average of 517 calories. The men who exercised in 91.4 degree water burned 505 calories, on average.

“We found that during the recovery period when the subjects had access to an assortment of foods that significantly more calories were eaten after exercise in cold water compared to exercise in warm water or at rest,” White said.
