Wolf Lake, MN 56575 Frost Dates
Wolf Lake, MN: when does the frost end?
Typically, the last spring freeze lands around 05/05, roughly 250 days out. Fall's first freeze usually shows up around 10/03, roughly 150 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Wolf Lake in Zone 3b (-35 to -30°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 5 weeks until Wolf Lake's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/05 isn't a guarantee
05/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/18 and only about 1 year in 10 sees frost after that.
