Jenks, OK 74132 Frost Dates
When can you plant in Jenks, OK?
Typically, the last spring freeze lands around 03/30, roughly 214 days out. The first fall frost typically arrives around 11/04, about 220 frost-free days later.
The USDA Plant Hardiness Zone Map puts Jenks 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 Jenks before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/30 isn't a guarantee
03/30 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. 04/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
