What Is a Snow Day Calculator?
A Snow Day Calculator is an online prediction tool that estimates the likelihood of school closures caused by severe winter weather. By combining local weather forecasts with common school-closing factors, it generates a simple percentage that tells you your chance of a snow day tomorrow.
Our calculator is designed for:
- Students & Parents – plan ahead and avoid early-morning surprises.
- Teachers – stay informed about potential cancellations.
- Commuters – check road safety risks in snowy conditions.
How Our Snow Day Calculator Works
The Snow Day Calculator 2025 uses live weather forecasts from WeatherAPI, including snowfall amounts, temperature, precipitation type, and wind speed. These factors are combined with typical regional school closure thresholds to estimate the chance of schools being closed.
Our prediction model is based on patterns observed in U.S. and Canadian school districts over the past several winters. For example, heavy overnight snowfall, icy road conditions, and prolonged freezing temperatures are weighted more heavily than light daytime flurries. This approach helps us provide a realistic estimate for your area.
Forecasts are refreshed several times per day during the winter season, so results may change as the weather updates. While we aim for accuracy, no online tool can guarantee school closures. Final decisions always rest with your local school district.
