Gallup, NM 87319 Frost Dates

When can you plant in Gallup, NM?

Zone 6a

Around 05/31 is the usual last spring frost, about 276 days away. The first fall frost typically arrives around 09/28, about 119 frost-free days later.

Gallup sits in USDA Zone 6a (-10 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 4 weeks of growing season left in Gallup before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/31 isn't a guarantee

05/31 is the middle of 30 years of NOAA records, not a promise. Plant by 05/15 and you're betting against frost in roughly 9 years out of 10. 06/14 is the safer bet, historically only a 1-in-10 chance of frost that late.
