Hottest May on Record in Atlanta

May 2019 turned out to be the hottest May on record in Atlanta, topping the previous hottest May, which was just last year in 2018.

5 Hottest Mays in Atlanta (based on average temperatures)

  1. 2019 - 76.4°
  2. 2018 - 74.8°
  3. 1996 - 74.8°
  4. 1896 - 74.7°
  5. 1899 - 74.5°

Why so hot?

A big reason why May was so hot was because of a huge dome of high pressure that parked itself over the southeast U.S., producing hot temperatures and dry weather. 

While high pressure is pretty common in the southeast U.S., the strength of this particular high was similar to a pattern we see more often in the summer, instead of May. 

Near-record number of 90-degree days

Atlanta ended up with 10 total 90-degree days in May, which was well above the average for May, which is two days.

The most number of 90-degree days on record for May is 11.
