Regional concentration

FL (16 cities), HI (3 cities), TX (3 cities), CA (2 cities) account for the most entries. The warmest U.S. cities cluster in a narrow band of the South and Southwest, with Key West, FL setting the benchmark. States outside this belt rarely appear because even a single cold season lowers the annual mean below the list threshold.

Temperature spread on this list

The gap between #1 and #25 on this list is only 3.7°F, meaning a single-degree shift in a station's 30-year mean can move it several positions. That sensitivity is why we show every tie at the cutoff rather than arbitrarily capping the list. The list median is 76.1°F.

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 perceived comfort; assess humidity separately because it is not an input to the climate comfort score. Humidity & comfort

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