I don’t know where in hawaii you were but:Oh, it was cold! Not too bad at first..but we were cold within a half an HR. In Mexico, we could stay in there for over an hr. and still be warm. Very warm from the get go.
At Honolulu on Oahu, the ocean stays as warm as a heated swimming pool all year long. Ocean temperatures do differ by a few degrees throughout the Hawaiian Islands, though. The water off Honolulu, for instance, is typically 5 °F (3 °C) warmer than at Hilo on the Big island.
