Climate change is causing heat waves to be even hotter and more common across the United States. Daily record-high temperatures from 2000 to 2009 were documented twice as frequently as record-lows, while those areas in the country with an excess of nine extreme-heat days experienced more such days than in the past.
On a global scale, a New York Times analysis of data released by NASA and the NOAA has shown that the last eight years are the hottest on record. Overall, cold days are becoming less frequent. Yet despite that fact, occurrences of unseasonable cold, as well as cooling trends in some regions of the country, still dot the national map.
Stacker ranked more than 900 counties in the 10 coldest states in the continental U.S. to find the warmest based on average temperature between May 2022 and April 2023, citing National Centers for Environmental Information data. The warmest states are Florida, Louisiana, Texas, Mississippi, Georgia, Alabama, South Carolina, Arkansas, Oklahoma, and North Carolina. Ties are broken based on the average low temperature. North Carolina counties dominate the forthcoming list, thanks to the mountainous terrain.
