Raleigh - Hottest Decades





Ranked here are the hottest decades on record for Raleigh, North Carolina. The lists include decades when Raleigh had the highest average temperatures, the most hot days and the fewest cold days. These extremes are for temperatures observed at Raleigh—Durham International Airport and cover seven decades, from the 1950s to the 2010s.

That is when Raleigh 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.
