Snow Day Calculator
Slide in tomorrow's forecast and your school type and we will estimate the chance of a snow day. Just for fun. Always check official announcements.
Pretty good chance. Pack a hot chocolate plan.
How to use it
- 1Enter your zip or postal code, or skip it. Then pick your school type. Rural districts close more often than urban private schools.
- 2Set the snow forecast in inches, the overnight temperature, and tomorrow's wind speed. The colder, snowier, and windier it is, the higher your chance.
- 3Add how many closures you have already had this week. Districts that have already burned through their snow budget are stricter about the next one.
About this tool
Snow day calculators are an end-of-year ritual for students from New England to Minnesota. They are not science. They are a playful reading of forecast plus pattern, designed to give a yes, no, or maybe answer when you are watching the snow fall and wondering if you can sleep in.
We weigh four signals. Forecast snowfall is the strongest. Cold temperatures matter because schools cancel for safety, not just for snow. High winds make plowed routes refreeze faster. Recent closures matter because districts try to preserve their snow-day budget. Mix them together with your school type, and you get a number to compare with friends.
Frequently asked
How accurate is this?
It is a fun estimator based on common-sense weather thresholds and historical patterns. It has no inside knowledge of your specific district or its policies. Use it for entertainment and check official announcements before assuming a day off.
Why do rural schools score higher than private?
Rural school buses cover much longer routes on country roads that take longer to plough. Private schools often serve a smaller commuter radius and tend to follow public-school cancellations rather than calling their own. We weight scores accordingly.
Does it work outside the United States?
The thresholds are calibrated for American school districts in cold-climate states. It can still be a fun guide for Canada, the UK, or Northern Europe. School cancellation policies vary widely so the absolute number is approximate.
Can I use this for college closures?
Colleges close less often than K-12 schools because they expect students and faculty to live nearby. The number you see will be optimistic for college closures.
Is anything sent to a server?
No. The whole calculator runs in your browser. Your zip code stays in this tab and is never logged.
