Achille, OK 74720 Frost Dates

When can you plant in Achille, OK?

Zone 8a

The last spring frost here typically falls around 03/19, about 203 days from today. The first fall frost typically arrives around 11/12, about 237 frost-free days later.

Achille sits in USDA Zone 8a (10 to 15°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 Achille before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/19 isn't a guarantee

03/19 is the middle of 30 years of NOAA records, not a promise. Plant by 03/01 and you're betting against frost in roughly 9 years out of 10. 04/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
