Texas has Hottest December
State climatologist John Nielsen-Gammon announced that Texas had its hottest December since at least 1889. The official state record for previous warmest December was December 1933, at 53.3 degrees and once the data is finalized, December 2021 may go into the record books with an average state temperature above 58 degrees Fahrenheit. In many of the states’ largest cities, temperatures were between 5-9 degrees warmer than average.
The 20th century average temperature for December in Texas is 46.9 degrees and Nielsen-Gammon believes that once data is finalized, the statewide average temperature for December 2021 will end up near 12 degrees above the 20th century average. Typically, temperatures are not compared to the century average, but instead the 30-year average. With our warming climate the 30-year average temperature for Texas is roughly two degrees warmer than the 20th century average.
