Deary, ID 83844 Frost Dates
Deary, ID: when does the frost end?
The last spring frost here typically falls around 05/15, about 260 days from today. Fall's first freeze usually shows up around 09/21, roughly 126 days after the last spring frost.
Deary 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 3 weeks until Deary's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/15 isn't a guarantee
05/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/02 and only about 1 year in 10 sees frost after that.
