Miami - Hottest Decades





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

That is when Miami 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.
