What is a snow day calculator?
A snow day calculator estimates the likelihood that your school district will close due to winter weather. Our snow day predictor analyzes the next 24 hours of weather forecast data including snowfall, temperature, ice risk, wind and storm timing to compute accurate predictions and snow day probability for your location.
Simply enter your zip code or city name above, and our accurate snow day calculator will pull real-time weather data from the National Weather Service. The tool considers multiple factors that school districts use when deciding closures, giving you reliable snow day predictions within seconds.
How we calculate your snow day probability
Our snow day predictor uses a sophisticated algorithm that weighs multiple weather factors to generate accurate snow day predictions. Here's what goes into each calculation:
- Snow accumulation: Higher totals raise the chance of school closures. The day calculator tracks expected snowfall over the next 24 hours.
- Timing: Overnight snow that hits the morning commute is more disruptive. Our snow day predictor factors in when precipitation will fall.
- Wind & drifting: Stronger gusts slow road clearing and reduce visibility, increasing closure probability.
- Temperature & ice: Near‑freezing temps mean icier roads and sidewalks, which school districts consider dangerous.
- Road conditions: Rural bus routes and poor road conditions are harder to treat, so risk increases for those areas.
Use this snow day calculator as a planning signal—always check official school district messages for final decisions. People often search for snow day calculator, snow day calc, snow day probability, or snow.day calculator—all roads point here for the most accurate predictions.

Accurate predictions powered by weather data
Our snow day calculator pulls weather forecast data directly from the National Weather Service via Open-Meteo. This ensures you're getting the same weather data that meteorologists and school districts use for their decisions. The result? Accurate snow day predictions you can trust.
The day calculator updates continuously as new weather forecast data becomes available, so you can check back multiple times as a storm approaches. Many users find that checking the snow day predictor the evening before gives them the most reliable forecast for the next morning.
