❄️ White Christmas Calculator
Wondering about your odds of a white Christmas this year? Enter a few facts about your local climate to get a rough probability estimate.
What counts as a “white Christmas”?
Meteorologists typically define a white Christmas as having at least an inch of snow on the ground on December 25, regardless of whether it’s actively snowing that day. Your odds depend heavily on local climate, elevation, and how cold a typical December has been.
How this estimate is calculated
The calculator weights your area’s historical rate of white Christmases most heavily, then adjusts based on your typical December 25 temperature (colder generally means better odds of snow staying on the ground), your region’s average annual snowfall, and a small bonus for higher elevations, which tend to hold snow longer.
This is a simplified, illustrative estimate for general interest and planning purposes, not an official weather forecast. Check your local meteorological service for actual forecasts closer to the date.
