Farmington, NM 87401 Frost Dates

When can you plant in Farmington, NM?

Zone 7a

The last spring frost here typically falls around 05/02, about 247 days from today. The first fall frost typically arrives around 10/13, about 160 frost-free days later.

Zone 7a (0 to 5°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 Farmington, not a forecast for this year.

What to do before the first frost

About 7 weeks of growing season left in Farmington before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

05/02 is the middle of 30 years of NOAA records, not a promise. Plant by 04/20 and you're betting against frost in roughly 9 years out of 10. 05/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
