Lawton, OK 73506 Frost Dates

When can you plant in Lawton, OK?

Zone 8a

Typically, the last spring freeze lands around 03/26, roughly 210 days out. The first fall frost typically arrives around 11/07, about 225 frost-free days later.

Lawton 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 10 weeks of growing season left in Lawton before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

03/26 is the middle of 30 years of NOAA records, not a promise. Plant by 03/04 and you're betting against frost in roughly 9 years out of 10. 04/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
