Climate

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).[43] 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 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.[44]
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. Southern Florida, however, rarely encounters freezing temperatures.[citation needed]
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.[45][46]
Due to its subtropical and tropical climate, Florida rarely receives snow. However, on rare occasions, a combination of cold moisture and freezing temperatures can result in snowfall in the farthest northern regions. Frost is more common than snow, occurring sometimes in the panhandle.[citation needed]
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.[47]

Florida's nickname is the "Sunshine State", but severe weather is a common occurrence in the state. Central Florida is known as the lightning capital of the United States, as it experiences more lightning strikes than anywhere else in the U.S.[54] Florida has one of the highest average precipitation levels of any state,[55] in large part because afternoon thunderstorms are common in much of the state from late spring until early autumn. A narrow eastern part of the state including Orlando and Jacksonville receives between 2,400 and 2,800 hours of sunshine annually. The rest of the state, including Miami, receives between 2,800 and 3,200 hours annually.[56]
Florida leads the United States in tornadoes per area (when including waterspouts)[57] but they do not typically reach the intensity of those in the Midwest and Great Plains. Hail often accompanies the most severe thunderstorms.[citation needed]
Hurricanes pose a severe threat each year during the June 1 to November 30 hurricane season, particularly from August to October. Florida is the most hurricane-prone state, with subtropical or tropical water on a lengthy coastline. Of the category 4 or higher storms that have struck the United States, 83% have either hit Florida or Texas.[58] From 1851 to 2006, Florida was struck by 114 hurricanes, 37 of them major—category 3 and above.[58] It is rare for a hurricane season to pass without any impact in the state by at least a tropical storm.[citation needed]
Florida was the site of what was then the costliest weather disaster in U.S. history, Hurricane Andrew, which caused more than $25 billion in damage when it struck in August 1992; it held that distinction until 2005, when Hurricane Katrina surpassed it. Hurricane Wilma — the second most expensive hurricane in Florida history — landed just south of Marco Island in October 2005.[59][60]
