Almont, MI 48003 Frost Dates

When can you plant in Almont, MI?

Zone 6a

Typically, the last spring freeze lands around 05/01, roughly 246 days out. The first fall frost typically arrives around 10/20, about 170 frost-free days later.

Almont 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 8 weeks of growing season left in Almont before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/01 isn't a guarantee

05/01 is the middle of 30 years of NOAA records, not a promise. Plant by 04/18 and you're betting against frost in roughly 9 years out of 10. 05/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
