Is Atlanta Getting Hotter?
It does seem that Atlanta is getting hotter. The summer of 2016 has been the second hottest summer, only second to 1980. September 3, 2016 was the first time in 73 days that the temperature in Atlanta will drop below 70 degrees F. Not only have the days been hot, but the usual cooling at night has not occurred making the night miserable. This 73 day stretch of not falling below 70 degrees is a record for Atlanta.
Atlanta’s eight hottest years have all come since 1980. In the summer of 2016, Atlanta had 75 days of high temperature of 90 F or above. The hot nights have been attributed to the lack of wind, due to high pressure systems. The humidity has also been higher than usual. High humidity keeps the nighttime temperatures from falling too much. Low humidity or dryer air allows the nighttime temperatures to cool.
Another cause of the very hot weather and warm overnight lows has also been cause by the lack of frontal systems or air mass changes.
To put 2016 into perspective from previous years as it pertains to the warm overnight lows, six of the 10 hottest stretches of summer ever recorded in Atlanta, when the low temperature never dipped below 70 degrees, have occurred since 2005.
The second longest streak of overnight lows not getting below 70 F was 55 days in 2010 and the third longest streak was 48 days in 2005. So the 73 days is quite a jump from the second longest streak.
