Bernalillo, NM 87004 Frost Dates

When can you plant in Bernalillo, NM?

Zone 7b

The last spring frost here typically falls around 04/17, about 232 days from today. The first fall frost typically arrives around 10/24, about 188 frost-free days later.

Zone 7b (5 to 10°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 Bernalillo, not a forecast for this year.

What to do before the first frost

About 8 weeks of growing season left in Bernalillo 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

04/17 is the middle of 30 years of NOAA records, not a promise. Plant by 04/02 and you're betting against frost in roughly 9 years out of 10. 05/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
