Main article: Climate of Florida

The climate of Florida is tempered somewhat by the fact that no part of the state is distant from the ocean. North of Lake Okeechobee, the prevalent climate is humid subtropical (Köppen: Cfa), while areas south of the lake (including the Florida Keys) have a true tropical climate(Köppen: Aw). Mean high temperatures for late July are primarily in the low 90s Fahrenheit (32–34 °C). Mean low temperatures for early to mid January range from the low 40s Fahrenheit (4–7 °C) in north Florida to above 60 °F (16 °C) from Miami on southward. With an average daily temperature of 70.7 °F (21.5 °C), it is the warmest state in the U.S.

In the summer, high temperatures in the state seldom exceed 100 °F (38 °C). Several record cold maxima have been in the 30s °F (−1 to 4 °C) and record lows have been in the 10s (−12 to −7 °C). These temperatures normally extend at most a few days at a time in the northern and central parts of Florida. South Florida, however, rarely encounters below freezing temperatures. The hottest temperature ever recorded in Florida was 109 °F (43 °C), which was set on June 29, 1931 in Monticello. The coldest temperature was −2 °F (−19 °C), on February 13, 1899, just 25 miles (40 km) away, in Tallahassee.

Due to its subtropical and tropical climate, Florida rarely receives measurable snowfall. However, on rare occasions, a combination of cold moisture and freezing temperatures can result in snowfall in the farthest northern regions like Jacksonville, Gainesville or Pensacola. Frost, which is more common than snow, sometimes occurs in the panhandle.The USDA Plant hardiness zones for the state range from zone 8a (no colder than 10 °F or −12 °C) in the inland western panhandle to zone 11b (no colder than 45 °F or 7 °C) in the lower Florida Keys. Fog also occurs all over the state or climate of Florida.
