Hottest cities in the U.S.
Ranked by NOAA 1991–2020 mean annual temperature across 3,917 U.S. cities and towns, every incorporated place and census-designated place with a mapped NOAA station.
Data updated July 2026
2 U.S. cities share the highest mean annual temperature, 78.8°F (NOAA 1991–2020 normals).
The 25 cities below include every tie at the 25-place cutoff and cluster in FL, HI, TX - subtropical coasts, the Hawaiian islands, and the desert Southwest reach a high annual mean by different routes. Rankings cover all 3,917 NOAA-tracked cities and towns over the same 30-year normals window.
The hottest U.S. cities, the verdict
2 U.S. cities share the highest annual mean of 78.8°F; equal values are co-leaders, ordered by city name only for stable display.

How this ranking is built
According to the National Oceanic and Atmospheric Administration (NOAA), a station's mean annual temperature is the 30-year average of its daily readings under the 1991–2020 U.S. Climate Normals program, published in May 2021. We rank the 3,917 U.S. cities and towns that carry a temperature normal, every incorporated place and census-designated place matched to a NOAA station, drawn from more than 15,000 stations, from warmest to coolest. Weather stations that never matched a Census place (national parks, airports, reservoirs and similar sites) are excluded: their readings are real, but they are not cities, and ranking them here would answer a different question than this page asks. Because these are long-run averages, a single hot summer day or record high does not change a record's position. The full derivation is documented in our methodology.
Caveats
Coastal and island locations stay warm year-round with little seasonal swing, while desert locations pair very hot summers with cooler nights and winters, two different routes to a high annual mean. Station coverage is sparser in some rural areas, and these normals end in 2020, so they do not capture warming since then. For monthly detail, frost dates, and humidity, open any location profile.
What a high annual mean really means
The warmest locations share a number, not a feel.
- Florida and Hawaii locations are humid and mild year-round; Southwest locations are dry with extreme summer peaks. Most comfortable
- Heat plus humidity drives comfort; check a location’s comfort score, not just its temperature. Humidity & comfort
- Looking for the opposite? See the coldest U.S. cities. Coldest cities
NOAA 1991–2020 normals are typical-year averages, not forecasts, and exclude post-2020 trends.
