Sacramento - Hottest Decades





Ranked here are the hottest decades on record for Sacramento, California. The lists include decades when Sacramento had the highest average temperatures, the most hot days and the fewest cold days. These extremes are for temperatures observed at the California State University campus in Sacramento and cover 14 decades, from the 1880s to the 2010s.

That is when Sacramento 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.
