Lincoln, MI 48742 Frost Dates

When can you plant in Lincoln, MI?

Zone 5b

Typically, the last spring freeze lands around 05/08, roughly 253 days out. The first fall frost typically arrives around 10/16, about 160 frost-free days later.

Lincoln sits in USDA Zone 5b (-15 to -10°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 7 weeks of growing season left in Lincoln before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/08 isn't a guarantee

05/08 is the middle of 30 years of NOAA records, not a promise. Plant by 04/26 and you're betting against frost in roughly 9 years out of 10. 05/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
