Herman, NE 68029 Frost Dates
Herman, NE: when does the frost end?
The last spring frost here typically falls around 04/28, about 243 days from today. Fall's first freeze usually shows up around 10/10, roughly 165 days after the last spring frost.
Zone 5b (-15 to -10°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 Herman, not a forecast for this year.
Stretching the season past the first frost
With roughly 6 weeks until Herman's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/28 isn't a guarantee
04/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/15 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/08 and only about 1 year in 10 sees frost after that.
