Has Sacramento ever had a white Christmas? Is it possible? Here’s what climate experts say
Imagine opening your eyes on Christmas morning to see your neighborhood blanketed by fluffy white snow.
It’s a scene you’ve probably watched countless times in holiday films.
But snow in Sacramento — let alone in December — is something of a unicorn.
According to the National Weather Service, a white Christmas is defined as at least 1 inch of snow on the ground on the morning of Christmas Day, Dec. 25.
In Sacramento, there’s a 0 to 10% chance of waking up to an accumulation of snow on the ground on Christmas Day, based on U.S. climate normals between 1981 and 2010, from the National Oceanic and Atmospheric Administration’s National Climate Data Center.
Greater chances of flurries are scattered along the coast and even parts of Southern California.
The most northern portion of the state as well as the mountains have between a 51% and 100% chance of snow — or a full-out winter storm — on Christmas.
Why doesn’t Sacramento see large amounts of snow?
Meteorologist Sara Purdue with the National Weather Service said the reason the capital city has never seen large amounts of snow is partly due to elevation.
The Sacramento Valley trends warmer.
The weather service has recorded trace amounts of snow in downtown Sacramento during January but never in December. Purdue said a trace is less than 100th of an inch.
“There’s a point when the snow is falling that it just melts because it’s too warm once it gets down here,” she said.
“You go 20 minutes east and you’re definitely more likely to see snow on Christmas.”
When it’s cold enough to snow in the capital city, the weather is typically clear. When there’s rain, the clouds trap heat from the day and create a warming effect not conducive for snow.
“The more energy that is trapped by the planet, the warmer our climate will grow,” NOAA’s Physical Sciences Laboratory said. “If less energy is collected, the climate will become cooler.
Roughly 1.5 inches of snow was recorded roughly 40 miles away from downtown Sacramento in Fairfield on Dec. 27, 1988.
A decade later, Sacramento Executive Airport received an unmeasurable amount of flurries.

Is snowfall possible in Sacramento?
Purdue said snow in Sacramento is “possible,” and The Sacramento Bee has proof to back that claim.
