Wilsonville, AL 35186 Frost Dates

When can you plant in Wilsonville, AL?

Zone 8a

Typically, the last spring freeze lands around 03/31, roughly 215 days out. The first fall frost typically arrives around 11/02, about 216 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 Wilsonville, not a forecast for this year.

What to do before the first frost

About 9 weeks of growing season left in Wilsonville before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/31 isn't a guarantee

03/31 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/16 is the safer bet, historically only a 1-in-10 chance of frost that late.
