Lake Aluma, OK 73190 Frost Dates
When can you plant in Lake Aluma, OK?
Around 04/02 is the usual last spring frost, about 217 days away. The first fall frost typically arrives around 11/05, about 217 frost-free days later.
The USDA Plant Hardiness Zone Map puts Lake Aluma 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 Lake Aluma before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/02 isn't a guarantee
04/02 is the middle of 30 years of NOAA records, not a promise. Plant by 03/12 and you're betting against frost in roughly 9 years out of 10. 04/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
