Chouteau, OK 74337 Frost Dates

When can you plant in Chouteau, OK?

Zone 7b

Typically, the last spring freeze lands around 03/29, roughly 213 days out. The first fall frost typically arrives around 11/05, about 223 frost-free days later.

The USDA Plant Hardiness Zone Map puts Chouteau in Zone 7b (5 to 10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 10 weeks of growing season left in Chouteau before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/29 isn't a guarantee

03/29 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. 04/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
