Historical Christmas snow depth gives a defensible starting point for your location. It answers how often at least one inch was on the ground on December 25 during the 1991–2020 climate-normal period.
Enter your city or ZIP to see how often Christmas starts with at least 1 inch of snow on the ground. That is a White Christmas—not a claim that snow will fall on December 25. As Christmas approaches, actual snowpack and the short-range forecast add the next signals.
