Driggs, ID 83012 Frost Dates
Driggs, ID: when does the frost end?
The last spring frost here typically falls around 06/24, about 300 days from today. Fall's first freeze usually shows up around 08/28, roughly 63 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 Driggs, not a forecast for this year.
Stretching the season past the first frost
With roughly any day now until Driggs'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
06/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 06/08 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 07/11 and only about 1 year in 10 sees frost after that.
