Omaha, TX 75558 Frost Dates
When can you plant in Omaha, TX?
Typically, the last spring freeze lands around 03/20, roughly 204 days out. The first fall frost typically arrives around 11/10, about 233 frost-free days later.
The USDA Plant Hardiness Zone Map puts Omaha in Zone 8b (15 to 20°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 11 weeks of growing season left in Omaha before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/20 isn't a guarantee
03/20 is the middle of 30 years of NOAA records, not a promise. Plant by 02/28 and you're betting against frost in roughly 9 years out of 10. 04/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
