About Idaho Winter Weather
Idaho has one of the most snow-hardened school cultures in the country. Across the 9 Idaho cities covered by SnowSense™, average annual snowfall is 42 inches, with Ketchum receiving up to 120 inches in a typical winter. Despite that volume, Idaho districts close school less often than mid-Atlantic districts do — kids, buses, and roads here are built for winter.
What closes Idaho schools isn't snow accumulation — it's wind chill, ice, or infrastructure failure. Sustained wind chills below −30°F trigger safety-driven cold-day cancellations under most Idaho districts' protocols. A foot of powder, by contrast, is usually just Tuesday.
The city links above show live snow day probability for every covered Idaho city. SnowSense™ weighs wind-chill risk separately from accumulation for Idaho, so a frigid-but-clear day can still register a probability spike when accumulation-only models would show zero.

What temperature closes schools in Idaho?
In Idaho, cold-day closures typically require wind chills below -30°F. Snow accumulation alone rarely closes schools here — districts are winter-hardened with plow fleets and cold-weather protocols.
How many snow days does Idaho typically get?
Despite heavy snowfall averaging 42 inches per year, Idaho districts typically use only 3–5 snow days per year because infrastructure handles routine snow efficiently.
