Milwaukee - Coldest Decades





The coldest decades on record are ranked here for Milwaukee, Wisconsin. The lists include decades when Milwaukee had the lowest average temperatures, the fewest hot days and the most cold days. These extremes are for temperatures observed at Mitchell International Airport near downtown Milwaukee and cover eight decades, from the 1940s to the 2010s.

That is when Milwaukee 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. An exception is the 2010s which so far includes data to the end of 2018.
