In total, 252 counties recorded their warmest Octobers on record last month, representing 10.7% of the U.S. population. A closer look at the data reveals a list of counties struggling with high heat throughout the South and other regions where daily average temperatures shattered prior October records last month.

To determine the places that just had their hottest Octobers on record, Climate Crisis 24/7 reviewed county-level data on average monthly temperatures from the NOAA’s National Centers for Environmental Information. All counties in the contiguous U.S. were ranked based on the difference in average daily temperature in October 2024 and the prior monthly record average. Only counties where October 2024 ranks as the hottest October on record – going back to 1895 – were included. Only counties with at least 100,000 residents were included.
