Nashville, Tennessee: freeze dates & growing season

Three different things get called “Nashville” here, so this page is explicit about all three: the metro label (Nashville), the anchor geography (Census ZCTA 37203, a downtown ZIP-code area), and the climate record (the NOAA station below). Windows are calculated from the station — not from your street address.

Climate basis: NOAA station Shelby Bottoms Nature, TN (USC00408238), 4 mi (6 km) from the ZCTA 37203 centroid, elevation 405 ft, on the 1991–2020 climate normals.

These windows describe typical years (1991–2020 climate normals), not this year's forecast. Freezes happen outside them — especially in frost pockets, valleys, and urban edges. Watch the forecast before committing tender plants.
