Frost dates for Kirtland, NM, ZIP 86507

Zone 7a

Around 05/03 is the usual last spring frost, about 248 days away. The first fall frost typically arrives around 10/17, about 163 frost-free days later.

The USDA Plant Hardiness Zone Map puts Kirtland in Zone 7a (0 to 5°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 7a around Kirtland has about 7 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 05/03 isn't a guarantee

05/03 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
