South Dakota Winter Profile
South Dakota has one of the most snow-hardened school cultures in the country. Across the 4 South Dakota cities covered by SnowSense™, average annual snowfall is 40 inches, with Sioux Falls receiving up to 42 inches in a typical winter. Despite that volume, South Dakota districts close school less often than mid-Atlantic districts do — kids, buses, and roads here are built for winter.
What closes South Dakota 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 South Dakota districts' protocols. A foot of powder, by contrast, is usually just Tuesday.
The city links above show live snow day probability for every covered South Dakota city. SnowSense™ weighs wind-chill risk separately from accumulation for South Dakota, so a frigid-but-clear day can still register a probability spike when accumulation-only models would show zero.
