Snow Day Calculator: How to Predict School Closures in Canada

Winter in Canada is beautiful, but it also brings heavy snowfall, icy roads, and school closures. Many parents and students wonder, “Will there be a snow day tomorrow?” A Snow Day Calculator can help predict school closures based on weather conditions.
This article will explain how a Snow Day Calculator works, how accurate it is, and how to use it. We’ll also share tips on staying prepared for snow days in Canada.

A Snow Day Calculator is an online tool that predicts the chances of schools closing due to snow. It uses weather data like:

By analyzing these factors, the calculator estimates the likelihood of a school closure in your area.
How Does It Work?

- Use this prediction to plan ahead.
While it’s a useful tool, official school announcements should always be checked.
