Snow Day Calculator for Massachusetts

Enter your ZIP code above for your district's chance of a closure or delay tomorrow, or pick a city below. Each district decides for itself; the calculator estimates the chance from tonight's National Weather Service forecast and updates hourly from the afternoon until morning.

It depends a lot on where you are: average yearly snowfall across Massachusetts ranges from 22 to 85 inches (NOAA 1991–2020 normals at weather stations near 539 ZIP codes). Among the largest places, Lowell averages 59 inches.

It varies by district and by how often each area gets snow. In the snowiest parts of Massachusetts, closures usually take several inches overnight; in places that rarely see snow, an inch or two can close schools. The calculator scales each storm by the local NOAA normal for your ZIP.
