Birmingham - Hottest Decades





Ranked here are the hottest decades on record for Birmingham, Alabama. The lists include decades when Birmingham had the highest average temperatures, the most hot days and the fewest cold days. These extremes are for temperatures observed at Birmingham—Shuttlesworth International Airport and cover nine decades, from the 1930s to the 2010s.

That is when Birmingham had weather measurements that are consistent and complete enough to compare decades. Each decade comprises a standard 10-year range. For instance, the 1990s includes measurements from Jan 1, 1990 to Dec 31, 1999. Links to the data behind these lists are in the References section on this page.
