Florida Temperature Records
- Hottest temperature ever recorded: 109 F, Monticello, northwestern Florida, 6/29/1931
- Coldest temperature ever recorded: -2 F, Tallahassee, northwestern Florida, 2/13/1899
- Hottest location ranked by highest average annual temperature: Key West, southern Florida, 77.8 F
- Coldest location ranked by lowest average annual temperature: Niceville, northwestern Florida, 66.0 F
- The summer of 1998 was Florida's hottest summer. During June, Melbourne, Florida broke 21 daily high
temperature records, experienced 24 days equal or above 90 degrees and 4 days equal or above 100 degrees
- Miami, Florida endured its hottest summer ever in 2010. The average temperature from June - August was
85.17 F. The temperature reached or exceeded 90 F degrees on 80 out of a possible 92 days. The low
temperature did not drop below 80F on 40 days, breaking the previous record of 33 days.
- Jacksonville, Florida experienced a unique year in climate during 2010. The period from January 1 to
March 30 was the coldest start to any year in Jacksonville's recorded history (going back to 1871).
Jacksonville's temperature through March 30 averaged 51.1 degrees, which was 5.7 degrees below normal
By July, record heat had arrived. From July 8 through August 26, the temperature equaled or exceeded
90 degrees for a record 50 consecutive days.
- Key West, Florida is considered the hottest city in the United States with an annual average temperature
of 77.8 F, but the city endured a historic cold wave from January 2 - 13, 2010. One of the longest and most
intense cold periods ever recorded, temperatures remained more than 10 degrees below normal each day,
while January 10th and 11th were over 20 degrees below normal. The record low maximum temperature
of 52 degrees observed on January 10th was the coldest high temperature recorded in Key West in almost
Florida is the second hottest state in the US, only Hawaii is warmer. In the winter, maximum temperatures throughout Florida are balmy compared with those of northern states. The mean maximum temperature in northern Florida during January is about 65 F while south of Lake Okeechobee it is approximately 76° F. Even in northern Florida between December and February on average the daily maximum temperature rises above 75° F between 20 and 30 % of the time and south of Lake Okeechobee the percentage exceeds 75 percent. Large water bodies, particularly the Atlantic Ocean and the Gulf of Mexico, and to a lesser degree large lakes like Okeechobee and Apopka are the major modifiers of the State’s temperature during all seasons, but particularly in the winter. Maximum temperatures in the winter on the peninsula, particularly the southern half, tend to be slightly higher on the Atlantic than the Gulf Coast, in part because on the east coast winds come off of the Atlantic and pass over the relatively warm Gulf Stream. Winter prevailing winds on the west coast are from the land, which is often cooler at that time of year than the water of the Gulf of Mexico.
Average maximum temperatures in the State begin to reach into the upper 80s in April, first in the interior of the peninsula. From there, these high temperatures spread out towards the coasts. The spatial advance of the "Dog Days of Summer" is retarded near the coast by sea breezes, which are most powerful during the summer. Average maximum temperatures rise above 88° F on the west coast during May and along most of the east coast in June. At times, helped by the easterly trade winds, sea breezes can reach more than 25 miles into the interior.
Miami-Dade County provides an excellent example of how the ocean, and specifically the sea breeze, modifies temperature. There are three weather stations close to each other; Miami Beach which is on the shore, Miami International Airport that is eight miles in the interior, and 40-Mile Bend, about 40 miles from the coast. The eight miles between Miami Beach and Miami International makes a significant difference in both average maximum and minimum temperatures. Throughout the year, maximum temperatures are at least two degrees higher at the airport, slightly more in the summer than the winter. Minimum temperatures are two to three degrees higher at the Miami Beach station than that at the airport during the colder months, but only one degree higher during the warmer months. 40-Mile Bend’s maximum temperature is higher than that of the airport in all months, and the minimum temperatures are lower.
