Fun & Novelty

Snow Day Calculator

A just-for-fun snow day probability estimator based on predicted snowfall, wind speed, temperature, and day of week. Not a real weather forecast.

What are the “odds” of a snow day?

This is a toy that weights snowfall, temperature, and wind the way a bored student might. It is not a forecast and not your district’s closing policy. Bus contractors, ice vs powder, and whether it is already a Wednesday before a holiday matter more than this slider.

For an actual forecast

Use the National Weather Service and your school’s alert system. Then come back here if you want a joke number to text the group chat.

Frequently Asked Questions

How does the snow day calculator work?
It's a fun estimate game that combines predicted snowfall, temperature, wind speed, and day of the week into a rough 'probability' score. It is not connected to any real weather data or school district decision-making.
Is this a real snow day predictor?
No — this is a novelty, just-for-fun tool. For actual weather forecasts, check a real weather service like weather.gov (US) or the Met Office (UK). For actual school closure decisions, check your local school district's announcements directly.
Why does temperature affect the score?
Colder temperatures (at or below freezing) tend to correlate with icier, more hazardous road conditions, so the fun formula gives a small score boost when the forecast low is 20°F or below.
Why does wind speed matter?
High winds can cause snow drifting and reduce visibility, which the formula treats as a factor that nudges the score up when wind speeds reach 20 mph or higher.
Does it matter if it's a weekday or weekend?
The formula gives a small boost to weekday 'odds' since that's when snow days are actually relevant to school schedules — on weekends, there's no school either way, which the calculator notes for you.
Where can I get an actual snow day forecast?
Check your local school district's website or social media for closure announcements, and use a legitimate weather service like weather.gov, the National Weather Service, or your regional meteorological office for real forecasts.
