Death Valley - Hottest Decades





Ranked here are the hottest decades on record for Death Valley, California. The lists include decades when Death Valley had the highest average temperatures, the most hot days and the fewest cold days. These extremes are for temperatures observed at Furnace Creek in Death Valley National Park and cover six decades, from the 1960s to the 2010s.

That is when Death Valley 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.
