great whites can swim in cold waters no problem. maybe they prefer 50 degree water but they can handle cold water no problems. I saw this shark show (this one time at band camp... lol) showing how the layer below their skin and above their muscle is covered with a network of thick veins carrying blood from deep inside their body... so the idea is that warm blood is pumped through this layer keeping them warmer then the surrounding water....
