Florida is most influenced by the Gulf Stream, resulting in warmer winter temperatures.

The Gulf Stream, a warm ocean current flowing from the Gulf of Mexico along Florida’s coast, plays a key role in moderating the state's climate. This current raises the temperature of the surrounding air, particularly in winter, preventing the state from experiencing cold, harsh winters like much of the northern U.S. Florida's proximity to the Gulf Stream, along with its subtropical location, contributes to its year-round warm climate, making it a popular destination for those seeking milder winters.
