Hottest States in the U.S.

All 50 states ranked by NOAA 1991–2020 mean annual temperature, statewide averages across every reporting city we track.

Data updated July 2026

Florida is the hottest U.S. state, at 72.6°F mean annual temperature (NOAA 1991–2020 normals).

Florida, Hawaii, Louisiana top the ranking at 72.6°F, 72.4°F, 67.3°F respectively, statewide averages across each state's NOAA-tracked station-mapped locations, so a state's hottest location record can run far hotter than its own average. All 50 states are ranked below from the same 30-year normals window.

The hottest U.S. states, the verdict

Florida is the hottest U.S. state by annual mean temperature at 73°F, a statewide average across its 165 tracked station-mapped locations.

How this ranking is built

According to the National Oceanic and Atmospheric Administration (NOAA), each state's average temperature is derived from the 1991–2020 U.S. Climate Normals for every station-mapped location we track within that state, published in May 2021. We average across all tracked location records per state and rank from hottest to coldest. A large state with both desert and coastal stations can show a wide internal range even with a moderate statewide average; open any state's page for its location-by-location breakdown. The full derivation is documented in our methodology.

Caveats

A statewide average reflects only the cities in our database with a complete NOAA normal, not the state's entire land area, coverage is denser in populated regions than in remote rural areas. These normals end in 2020 and do not capture any warming trend since then. For a specific city's own numbers, humidity, and seasonal detail, open its city page.

What a state average hides

A statewide number is a starting point, not the whole picture.

NOAA 1991–2020 normals are typical-year averages, not forecasts, and exclude post-2020 trends.

Frequently Asked Questions

What is the hottest U.S. state by average temperature?
Florida has the highest statewide average annual temperature of any U.S. state, 73°F across NOAA's 1991-2020 Climate Normals.
Are the hottest states clustered in one region?
The top three, Florida, Hawaii, Louisiana, are all in the Deep South and Southwest -- consistent with the well-documented latitude and desert-climate pattern behind U.S. regional temperature extremes.
