Garvin, OK 74736 Frost Dates

When can you plant in Garvin, OK?

Zone 8a

Around 03/20 is the usual last spring frost, about 204 days away. The first fall frost typically arrives around 11/10, about 233 frost-free days later.

Garvin 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 Garvin before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/20 isn't a guarantee

03/20 is the middle of 30 years of NOAA records, not a promise. Plant by 02/28 and you're betting against frost in roughly 9 years out of 10. 04/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
