The climate of Florida is tempered by the fact that no part of the state is very distant from the ocean. North of Lake Okeechobee, the prevalent climate is humid subtropical, while coastal areas south of the lake (including the Florida Keys) have a true tropical climate.[6] 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 northern Florida to the mid-50s (≈13 °C) in southern Florida.
Fall foliage in North Florida
In the summer, high temperatures in the state seldom exceed 100 °F (38 °C). During the late autumn and winter months, Florida has experienced occasional cold fronts that can bring high winds and relatively cooler temperatures for the entire state, with high temperatures that could remain into the 40s and 50s (4 to 15 °C) and lows in the 20s and 30s (−7 to 4 °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. Southern Florida, however, rarely encounters sub-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.
South Florida's climate is ideal for growing sugarcane.
The USDA Plant hardiness zones for the state range from zone 8a (no colder than 10 °F (−12 °C) ) in the Crestview to zone 10b (no colder than 35 °F (2 °C) ) in Southeast Florida.[7]
During El Nino there is greater rainfall between November to March. At the end of El Nino in 1998 480 wildfire occurred.
The seasons in Florida are determined more by precipitation than by temperature, with the hot, wet springs and summers making up the wet season, and mild to cool, and the relatively dry winters and autumns, making the dry season. Fall foliage appears in Central and North Florida starting around late November, and into winter.
The Florida Keys, because they are completely surrounded by water, have lesser variability in temperatures. At Key West, temperatures rarely exceed 95 °F (35 °C) in the summer or fall below 55 °F (13 °C) in the winter, and frost has never been reported in the Keys.
