Wisner, LA 71243 Frost Dates

When can you plant in Wisner, LA?

Zone 8b

Typically, the last spring freeze lands around 03/10, roughly 194 days out. The first fall frost typically arrives around 11/16, about 250 frost-free days later.

Wisner sits in USDA Zone 8b (15 to 20°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 11 weeks of growing season left in Wisner before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/10 isn't a guarantee

03/10 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 03/31 is the safer bet, historically only a 1-in-10 chance of frost that late.
