DENVER (Stacker) — 2021 and 2022 saw some of the hottest temperatures ever recorded, as across the country extreme heat waves wreaked havoc on communities accustomed to more moderate weather.

For many regions, the consequences were grave: in the 2021 Western heatwave, hundreds lost their lives, largely due to a lack of air conditioning, and wildfires ravaged the area.

2022 temperatures compared to the 100-year average

While not every county in the nation has experienced such extreme heat, climate change has dramatically changed the heat landscape in nearly every state, including Colorado. Stacker identified the counties in Colorado with the greatest departure from average temperatures from December 2021 to November 2022 compared to the 1901-2000 average.

The average temperature over the past year served as a tiebreaker, according to data from the National Oceanic and Atmospheric Administration’s National Center for Environmental Information. Additional data on recent average high and low temperatures for each county is also included.
