How much will it snow in DC this winter? Play our prediction game.

Remark

As the DC region climbs out of an early-season cold snap and approaches Thanksgiving, the December 1st meteorological winter’s onset is now just over a week away.

If you’ve read our winter forecasts, you’ll know that we don’t favor significant snowfall locally. But we’ve been wrong before.

Until 11 p.m. Tuesday, November 30, you can enter your forecast for how much snow you expect from December 1 through March 31 at Reagan National Airport (Washington’s official measurement location), to the nearest tenth of an inch. If snow falls before December 1, it will not count towards the total.

Simply fill out the form below to participate.

There is no prize for this contest, but the winner(s) will be recognized here on the Capital Weather Gang in the spring.

For the winter of 2021-2022, almost 900 people participated. Six accurately predicted 13.2 inches to fall. The group’s average prediction was 12.2 inches, which was only an inch difference. About 100 participants were within an inch of the target.

As a reminder, the Capital Weather Gang’s winter forecast calls for six to twelve inches of snow at National Airport and much of the area south and east of the city. North and west, higher amounts are predicted. As usual, this and all seasonal precipitation forecasts are not very reliable.

Some extra background can help you with your snowfall forecast:

  • The current weather service average is 13.7 inches for the entire cold season in the city. On average, there is 0.1 inch in November, 4.7 inch in December, 4.9 inch in January, 5.0 inch in February, and 2.0 inch in March. The median for the past 30 winters is 10.9 inches.
  • The long-term average, back to 1888, is about 18 inches. 100 years ago, the average was nearly 24 inches per winter.

Below is the total snowfall for the last five winters, and here’s the whole history:

  • 2021-2022… 13.2 inches
  • 2020-2021… 5.4 inches
  • 2019-2020…16.9 inches
  • 2018-2019…7.8 inches
  • 2017-2018…3.4in

Good luck and think snowy (or not)!
