Tennessee The hottest temperature ever recorded in Tennessee, 113 degrees Fahrenheit, was recorded at Perryville on July 29 and August 9, 1930. The National Weather Service reports that this is still the state’s official all-time high.
Nashville’s record of 109 F, set on June 29, 2012, comes in second.
Several Tennessee cities saw record-breaking temperatures during the North American heat wave that lasted from late June to early July 2012: Knoxville achieved 105°F, Memphis 108°F, and Chattanooga 107°F.
These peaks from history show how hot summer temperatures may get all the way into Tennessee.
Other significant cities consist of:
-
Memphis
: recorded 108 F on July 13, 1980, part of the severe 1980 United States heat wave -
Knoxville
: peaked at 105 F on June 30 and July 1, 2012.
These records continue to influence our understanding of Tennessee’s susceptibility to high heat events that pose serious dangers to ecosystems, infrastructure, and public health, even though they mostly span the early 20th century and the mid-1980s to the early 2010s.
