What is a snow day calculator?

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.

Snow day probability scale

Our snow day predictor uses a five-tier system to communicate closure likelihood:

0% - No chance due to low precipitation
0%-55% - Little to no chance, but possible
55%-75% - Delay likely
75%-87% - Possibility of no school
87%-99% - No school or possible early dismissal

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.
