About This Data
Probabilities are based on NOAA 30-year climate normals (1981-2020) for US cities and Environment and Climate Change Canada data for Canadian cities. Results show the historical likelihood of at least 1 inch of snow on the ground on December 25.

Will It Snow on Christmas? The White Christmas Calculator Can Tell
Every year, as December approaches, the same hopeful question circulates among families and friends: will we have a white Christmas? The dream of waking up to a snow-covered landscape has been celebrated in songs like Bing Crosby’s “White Christmas” and Wham!’s “Last Christmas,” yet for many it remains an annual guess. The White Christmas Calculator turns this guessing game into a data-driven forecast, letting you check the Christmas snow probability for your city based on decades of historical weather records.
How the Snowfall Probability Is Determined
The tool relies on 30‑year climate normals from the National Oceanic and Atmospheric Administration (NOAA) for U.S. locations and Environment and Climate Change Canada for Canadian locations (period 1981‑2020). It analyzes data from thousands of weather stations to produce four key outputs:
- Probability of Snow – the percentage chance that at least 1 inch of snow will be on the ground on December 25. This is the official meteorological definition of a white Christmas.
- Typical Snow Depth – the median snow depth observed on the same date over those 30 years. This gives you a realistic idea of how much snow you can usually expect.
- Probability of Snowfall – the chance that new snow will actually fall on Christmas Day (available only for U.S. cities).
- Typical Snowfall – the median amount of new snowfall on December 25 (also U.S.‑only).
These historical probabilities serve as a reliable guide, but keep in mind that actual weather patterns can cause year‑to‑year variation. For the most accurate short‑term forecast, check local predictions a few days before the holiday.
Where Your White Christmas Probability Is Highest
If you’re determined to celebrate in a winter wonderland, certain cities offer historical odds above 90 %. In the United States, the top locations with the highest white Christmas probability include:
- Bettles (Alaska)
- Aspen (Colorado)
- Hayden (Colorado)
- Rangeley (Maine)
- Fort Kent (Maine)
- Marquette (Michigan)
- Duluth (Minnesota)
- International Falls (Minnesota)
- Newcomb (New York)
- West Burke (Vermont)
In Canada, the picture is even brighter. Iqaluit, Kenora, Whitehorse, Winnipeg, and Yellowknife boast near‑100 % historical odds. They are closely followed by Brandon, Goose Bay, Timmins, and Thunder Bay at 95 %. Across the country, Canadian cities have a 68 % average chance of a white Christmas. The major exception is Vancouver, with only a 10 % probability – meaning a white Christmas there happens roughly once every ten years.
A Practical Example: Using the Snow Depth Calculator for Minneapolis
Imagine you’re spending the holidays in Minneapolis, Minnesota. After selecting the country, state, and city, the white Christmas probability tool shows:
- Probability of snow: 74 %
- Typical snow depth: 5 inches
- Probability of snowfall: 30 %
- Typical snowfall: 0.6 inches
A 74 % chance means snow is likely, and 5 inches is enough to build a snowman. However, it is not enough to build an igloo. The calculator also suggests up to four alternative destinations with a probability at least 20 % higher than your current city. For Minneapolis, Anchorage, Alaska, comes out on top – offering a 22 % boost in your chance of seeing snow.
Fun Add‑Ons: Igloo Feasibility and Last White Christmas
Beyond the core numbers, the tool includes a few playful features. It can tell you whether the typical snow depth in your city exceeds 10 inches – the minimum compacted snow layer needed to construct an igloo. Snow is an excellent insulator; its air pockets can keep the interior temperature between 19 °F and 61 °F even when outside temperatures drop to –49 °F. The calculator also shows the last year your city had a white Christmas (where historical data permits), adding a nostalgic touch to your holiday planning.
The Remarkable White Christmas of 2017
Some years stand out. Thanks to a series of late‑December snowstorms, 2017 delivered the most widespread snow cover in the lower 48 states in five years. Seattle experienced only its sixth white Christmas since the 1890s, and Portland, Oregon, matched that rarity. It was also the fifth most widespread white Christmas in a 15‑year NOAA database. Such infrequent events highlight how special a truly snowy Christmas morning can be.
Record‑Low Christmas Night Temperatures
Snow and cold often go hand‑in‑hand. The table below lists the coldest temperature ever recorded on Christmas night for selected U.S. cities.

|---|---|---|
| Northeast | Caribou, ME | –26 |
| Northeast | Boston | –8 |
| Northeast | New York City | –1 |
| Northeast | Syracuse, NY | –22 |
| Northeast | Pittsburgh | –12 |
| Northeast | Washington, DC | 3 |
| South | Raleigh, NC | 4 |

FAQ
1. How does the White Christmas Calculator define a white Christmas?
The calculator defines a white Christmas as having at least 1 inch of snow on the ground on December 25. This is the standard meteorological definition used by NOAA and Environment Canada.
2. Which Canadian city has the lowest probability of a white Christmas?
Vancouver has the lowest historical probability at 10%, meaning a white Christmas occurs there roughly once every ten years.
3. Can I use the tool to check if there is enough snow to build an igloo?
Yes, the calculator compares the typical snow depth to the 10-inch threshold needed for building an igloo. If the depth exceeds 10 inches, it indicates igloo construction is possible.
4. Why are snowfall probability and typical snowfall only available for U.S. cities?
The data for those two metrics come from NOAA’s U.S. weather stations. Equivalent data from Environment and Climate Change Canada are not available, so they are omitted for Canadian locations.
5. What was unusual about the white Christmas in 2017?
Late-December snowstorms produced the most widespread snow cover in the lower 48 states in five years. Many cities, including Seattle and Portland, experienced only their sixth white Christmas since the 1890s.
