Houston - Coldest Decades





The coldest decades on record are ranked here for Houston, Texas. The lists include decades when Houston had the lowest average temperatures, the fewest hot days and the most cold days. These extremes are for temperatures observed at the William P. Hobby Airport near downtown Houston and cover seven decades, from the 1950s to the 2010s.

That is when Houston 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.
