Enderlin, ND 58027 Frost Dates
Enderlin, ND: when does the frost end?
Around 05/03 is the usual last spring frost, about 248 days away. Fall's first freeze usually shows up around 10/05, roughly 155 days after the last spring frost.
Zone 4a (-30 to -25°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Enderlin, not a forecast for this year.
Stretching the season past the first frost
With roughly 5 weeks until Enderlin's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/03 isn't a guarantee
05/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/16 and only about 1 year in 10 sees frost after that.
