Amarillo, TX 79106 Frost Dates
When can you plant in Amarillo, TX?
Typically, the last spring freeze lands around 04/13, roughly 228 days out. The first fall frost typically arrives around 10/27, about 195 frost-free days later.
Amarillo sits in USDA Zone 7a (0 to 5°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 9 weeks of growing season left in Amarillo before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/13 isn't a guarantee
04/13 is the middle of 30 years of NOAA records, not a promise. Plant by 03/29 and you're betting against frost in roughly 9 years out of 10. 04/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
