California snow day questions
Will schools in California be closed tomorrow?
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.
How much snow falls in California?
It depends a lot on where you are: average yearly snowfall across California ranges from 0 to 445 inches (NOAA 1991–2020 normals at weather stations near 1,803 ZIP codes). Among the largest places, Los Angeles averages 0 inches.
How much snow closes schools in California?
Not much. Where snow is rare, districts often close or delay for an inch or two, and for ice. The calculator scales each storm by the local normal, so the same inch counts for more here than in a snowy state.
