Zone 8a

The last spring frost here typically falls around 03/16, about 200 days from today. The first fall frost typically arrives around 11/16, about 244 frost-free days later.

Zone 8a (10 to 15°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 Memphis, not a forecast for this year.

What to do before the first frost

Zone 8a around Memphis has about 11 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 03/16 isn't a guarantee

03/16 is the middle of 30 years of NOAA records, not a promise. Plant by 02/27 and you're betting against frost in roughly 9 years out of 10. 04/04 is the safer bet, historically only a 1-in-10 chance of frost that late.
