Frost dates for Roy, NM, ZIP 87730
Around 04/30 is the usual last spring frost, about 245 days away. The first fall frost typically arrives around 10/11, about 164 frost-free days later.
The USDA Plant Hardiness Zone Map puts Roy in Zone 6b (-5 to 0°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 6b around Roy has about 6 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 04/30 isn't a guarantee
04/30 is the middle of 30 years of NOAA records, not a promise. Plant by 04/17 and you're betting against frost in roughly 9 years out of 10. 05/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
