Frost dates for Elk City, OK, ZIP 73644
Typically, the last spring freeze lands around 04/05, roughly 220 days out. The first fall frost typically arrives around 11/04, about 210 frost-free days later.
The USDA Plant Hardiness Zone Map puts Elk City 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
Zone 7b around Elk City has about 10 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
