Roswell, NM 88203 Frost Dates
Frost dates for Roswell, NM, ZIP 88203
Typically, the last spring freeze lands around 03/29, roughly 213 days out. The first fall frost typically arrives around 11/07, about 223 frost-free days later.
The USDA Plant Hardiness Zone Map puts Roswell 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
Zone 7b around Roswell has about 10 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 03/29 isn't a guarantee
03/29 is the middle of 30 years of NOAA records, not a promise. Plant by 03/08 and you're betting against frost in roughly 9 years out of 10. 04/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
