Floridian here! I've been taking cold showers as well for the past few years and I can certainly say it makes a difference in the way you feel afterwards compared to a normal hot shower and regardless of the weather of the day as well, obviously it's more enjoyable when it is a warmer day or after some physical activity and exercise.

As some mentioned I think it has more to do with the shock put on your body which releases endorphins and other chemicals beneficial for brain function, it has shown to also be beneficial for some suffering from depression and such [1][2].
