White Christmas
Will Big Sky, MT have a white Christmas?
Big Sky, Montana had snow on the ground on Christmas morning in 17 of the 27 Christmases measured from 1996 to 2025. The last white Christmas there was in 2023.
Measured at Ennis, 17 miles west of Big Sky. That station is far enough from Big Sky, or high or low enough, that this is its own record rather than a call for the town. A white Christmas is an inch or more of snow on the ground at the Christmas morning reading, the line NOAA uses, counted from the station's own daily record.
The forecast for Christmas morning in Big Sky starts on this page on December 18.
