Dougherty, OK 73032 Frost Dates
When can you plant in Dougherty, OK?
Around 04/04 is the usual last spring frost, about 219 days away. The first fall frost typically arrives around 11/01, about 212 frost-free days later.
The USDA Plant Hardiness Zone Map puts Dougherty in Zone 8a (10 to 15°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 9 weeks of growing season left in Dougherty before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/04 isn't a guarantee
04/04 is the middle of 30 years of NOAA records, not a promise. Plant by 03/15 and you're betting against frost in roughly 9 years out of 10. 04/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
