Minneapolis, MN 55404 Frost Dates

Frost dates for Minneapolis, MN, ZIP 55404

Zone 5a

Typically, the last spring freeze lands around 04/23, roughly 238 days out. The first fall frost typically arrives around 10/16, about 175 frost-free days later.

The USDA Plant Hardiness Zone Map puts Minneapolis in Zone 5a (-20 to -15°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

Zone 5a around Minneapolis has about 7 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

How much risk comes with planting early here

04/23 is the middle of 30 years of NOAA records, not a promise. Plant by 04/10 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
