Why does Key West have warm waters year round?

Key West’s year-round warm water temperatures can be attributed to its strategic geographical location and the influence of the Gulf Stream. Positioned at the southernmost point of the United States, Key West enjoys a tropical climate characterized by mild winters and warm summers. The nearby Gulf Stream, a powerful warm ocean current originating in the Gulf of Mexico, acts as a natural thermostat for the surrounding waters. This current brings consistently higher temperatures to the region, preventing extreme fluctuations in water temperature throughout the year. The result is a paradise where visitors can relish the luxury of comfortably warm waters, making Key West an ideal destination for those seeking aquatic adventures in any season.
