Halsey, NE 69157 Frost Dates
Halsey, NE: when does the frost end?
Around 05/09 is the usual last spring frost, about 254 days away. Fall's first freeze usually shows up around 10/02, roughly 143 days after the last spring frost.
Zone 5a (-20 to -15°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 Halsey, not a forecast for this year.
Stretching the season past the first frost
With roughly 5 weeks until Halsey's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/09 isn't a guarantee
05/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/22 and only about 1 year in 10 sees frost after that.
