Tennessee frost dates

Across 148 NOAA climate stations in Tennessee, the median last spring frost (32°F) ranges from Mar 16 at Memphis Intl AP to May 22 at Mt Leconte; the typical station sees its last frost around Apr 7 and its first fall frost around Oct 29.

“Median” dates have a 50% chance of a later spring frost or an earlier fall frost. “10% risk” dates are the safer choice for tender plants: only 1 year in 10 has frost beyond them. Source: NOAA NCEI 1991–2020 Climate Normals. Elevation matters: within a state, frost dates can differ by a month or more between valleys and hills.
