Deer Creek, MN 56527 Frost Dates
Deer Creek, MN: when does the frost end?
Around 05/10 is the usual last spring frost, about 255 days away. Fall's first freeze usually shows up around 09/30, roughly 141 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Deer Creek in Zone 4a (-30 to -25°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 Deer Creek's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/10 isn't a guarantee
05/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/25 and only about 1 year in 10 sees frost after that.
