Warmest US Cities in Winter
During December, January and February, large cities with the warmest climates in the United States are in Florida. Just slightly cooler are urban areas along California's Pacific coast and in southern Arizona and Texas.
The season's hottest temperatures are at Florida's southernmost city, Miami. Nearly every winter day in Miami reaches at least 60 degrees Fahrenheit (15 °C). The city's temperature climbs into the 80s on 40 percent of the days in December, January and February.
These rankings of hottest cities use long-term temperature averages, based on weather data collected from 1981 to 2010 for the NOAA's National Climatic Data Center.
