Council, ID 83612 Frost Dates
When can you plant in Council, ID?
The last spring frost here typically falls around 05/10, about 255 days from today. The first fall frost typically arrives around 10/02, about 145 frost-free days later.
Zone 6a (-10 to -5°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 Council, not a forecast for this year.
What to do before the first frost
About 5 weeks of growing season left in Council before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/10 isn't a guarantee
05/10 is the middle of 30 years of NOAA records, not a promise. Plant by 04/25 and you're betting against frost in roughly 9 years out of 10. 06/01 is the safer bet, historically only a 1-in-10 chance of frost that late.
