Hobart, OK 73651 Frost Dates

When can you plant in Hobart, OK?

Zone 7b

Typically, the last spring freeze lands around 04/07, roughly 222 days out. The first fall frost typically arrives around 11/04, about 209 frost-free days later.

The USDA Plant Hardiness Zone Map puts Hobart 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 Hobart 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

04/07 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.
