Those hot and humid Miami summers are projected to get substantially more hot and humid as we gallop towards the end of the century and continue to endure rising greenhouse gas emissions. According to a study by Climate Central, Miami's average temperature in the summer of 2100 is expected to hit 95 degrees, similar to that of Harlingen, Texas, and up from the 88.6 degrees we see today. Meanwhile Boston's current average summer temperature of 79 degrees is expected to climb all the way to the 89-degree averages you currently see in North Miami Beach.
The study found summer heat is expected to warm 7-10 degrees on average across the United States. Now whether parts of Miami will be above sea level in 2100 is another discussion entirely.
