Warmest US Cities in Winter

The clear front runner among large US cities for hot winter weather during December, January and February is Miami, Florida. Depending how you measure things, Tampa and Orlando also rank high. Other winter hot spots are scattered from Louisiana to California. By looking at temperatures from various angles, this page ranks the hottest major cities in winter.

The lists of hottest cities use long-term temperature averages for the three winter months, December, January and February, based on weather data collected from 1991 to 2020 for the US National Centers for Environmental Information. The major cities included in these weather rankings represent the 51 metropolitan areas in the United States with the most people, all those with over one million residents in 2010, according to the US Census Bureau.

Hottest Winter Days

Temperatures during winter at American cities don't reach into the 100s, and 90-degree weather is rare. Just five cities have briefly reached 90 degrees at this time of year: Austin, Dallas, San Antonio, Los Angeles and Riverside.

At least a day of 80-degree weather usually shows up during winter at 13 major cities. The same cluster of cities are also the only ones to have over 12 days during a typical winter when the thermometer rises to 70 °F or more. Yet for most of those cities, days in the 60s are more the norm.

The warm–winter cities are mainly concentrated in Florida, California and Texas. Among the group, only Miami, Tampa and Orlando have a daily high that averages above 70 during winter.

The cities listed below most often see temperatures above 70 or 80 degrees during winter.

Warmest Winter Nights

While freezing weather is a reality during winter in many American cities, that's not true for all. Freezing temperatures are not at all expected in Miami, Los Angeles, San Diego and San Francisco, and are a rare event in Phoenix and Tampa. In fact, at those cities plus a few others, it's not often that temperatures even drop below 40 °F on a winter's night.

At the other end of the scale, every night during the season does cool down to 70 in every major US city except in Miami. The Florida winter destination averages 16 nights a winter with temperatures above 70 degrees, and most winter nights end up in the 60s F (above 16 °C).

The list below ranks major US cities which average fewer than 30 nights a winter with temperatures of 40 °F or below.
