Florida - The climate of Florida is tempered somewhat by its proximity to water. Most of the state has a humid subtropical climate, except for the southern tip which borders on tropical and the Florida Keys which have a true tropical climate. Cold fronts can occasionally bring high winds and cool to cold temperatures to the entire state during late fall and winter. One such front swept through the peninsula on November 25, 1996, bringing cold temperatures and winds up to 95 miles per hour (150 km/h), knocking out power to thousands and damaging mobile homes. The seasons in Florida are actually determined more by precipitation than by temperature with mild to cool, relatively dry winters and autumns (the dry season) and hot, wet springs and summers (the wet season). The Gulf Stream has a moderating effect on the climate, and although much of Florida commonly sees a high summer temperature over 90 degrees Fahrenheit (32 °C), the mercury seldom exceeds 100 degrees Fahrenheit (39 °C).
