Remer, MN 55745 Frost Dates

When can you plant in Remer, MN?

Zone 4a

Around 05/08 is the usual last spring frost, about 253 days away. The first fall frost typically arrives around 10/01, about 144 frost-free days later.

The USDA Plant Hardiness Zone Map puts Remer in Zone 4a (-30 to -25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 5 weeks of growing season left in Remer 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 04/28 and you're betting against frost in roughly 9 years out of 10. 05/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
