Dallas, TX 75355 Frost Dates
When can you plant in Dallas, TX?
Typically, the last spring freeze lands around 03/02, roughly 186 days out. The first fall frost typically arrives around 11/29, about 272 frost-free days later.
Zone 8b (15 to 20°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Dallas, not a forecast for this year.
What to do before the first frost
About 13 weeks of growing season left in Dallas before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/02 isn't a guarantee
03/02 is the middle of 30 years of NOAA records, not a promise. Plant by 02/10 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
