Our snow day calculator predicts the likelihood of school closures and delays based on real-time weather data for your area. Enter your zip code, choose your school type, and get an instant probability estimate powered by snowfall forecasts, ice accumulation, wind chill, and historical closure patterns for your region.
The calculator analyzes weather forecast data for your specific location, including expected snowfall totals, ice accumulation, wind speed, and temperature. It combines this with your school type and district-level closure history to estimate a probability that school will be cancelled or delayed the next day.
Accuracy improves as the weather event gets closer. Predictions made the evening before tend to be the most reliable because weather models are most accurate within a 12-24 hour window. We recommend checking again before bed for the most up-to-date probability.
The biggest factors are total snowfall amount and timing relative to the morning commute. Ice accumulation, wind chill advisories, road conditions, bus route accessibility, and your district's historical threshold for closures all play a role. Rural districts with longer bus routes tend to close more readily than urban ones.
Currently we support US and Canadian zip codes. The calculator uses National Weather Service data for US locations and Environment Canada forecasts for Canadian locations.
A snow day means school is fully cancelled for the day. A delay (usually 1-2 hours) means school starts later than normal to give road crews time to clear routes. Our calculator factors in delay likelihood as part of the overall closure probability.
The best time is between 7-10 PM the night before. By then, weather models have locked in on the storm track and snowfall totals, giving you the most accurate prediction. Checking again early in the morning (around 5 AM) can also catch any overnight forecast changes.
