Hansen, ID 83334 Frost Dates
Hansen, ID: when does the frost end?
The last spring frost here typically falls around 05/06, about 251 days from today. Fall's first freeze usually shows up around 10/03, roughly 150 days after the last spring frost.
Hansen sits in USDA Zone 6b (-5 to 0°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 5 weeks until Hansen's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
05/06 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/22 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/26 and only about 1 year in 10 sees frost after that.
