Dandridge, TN 37725 Frost Dates

Frost dates for Dandridge, TN, ZIP 37725

Zone 7b

Typically, the last spring freeze lands around 04/24, roughly 239 days out. The first fall frost typically arrives around 10/17, about 175 frost-free days later.

Zone 7b (5 to 10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Dandridge, not a forecast for this year.

What to do before the first frost

Zone 7b around Dandridge has about 7 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 04/24 isn't a guarantee

04/24 is the middle of 30 years of NOAA records, not a promise. Plant by 04/10 and you're betting against frost in roughly 9 years out of 10. 05/13 is the safer bet, historically only a 1-in-10 chance of frost that late.
