How accurate are the predictions?
Our predictions are based on real-time weather data and advanced algorithms, but they are estimates, not guarantees. We typically achieve 70-80% accuracy for weather-related school closures. Always check with your school district for official closure announcements.
What areas do you cover?
We provide snow day predictions for all locations across the United States and Canada. Simply enter your city name or ZIP code to get started.
How does the calculator work?
Our calculator analyzes multiple weather factors including:
- Snowfall amount (heavy snowfall adds +40%)
- Temperature (below 20°F adds +20%)
- Wind speed (above 15 mph adds +10%)
- School level (elementary schools close more readily)
These factors are combined to calculate a probability percentage for each day.
Is this service free?
Yes! Snow Day Calculator & Predictor is completely free to use. There are no hidden fees, subscriptions, or premium features.
How far ahead can I check?
Our tool provides a 5-day forecast, giving you plenty of time to plan ahead for potential snow days.
Can I use this for college or work?
While designed primarily for K-12 schools, you can select "College" as your school level. The predictions consider that colleges and workplaces typically close less frequently than elementary schools.
Why does it show 0% on weekends?
Weekends automatically show 0% probability because there's typically no school on Saturdays and Sundays. The prediction focuses on regular school days.
What if my location isn't found?

How often is the data updated?
Weather data is updated in real-time from our weather provider. For the most current predictions, we recommend checking the calculator each morning.
