Snow Stats

Seattle averages just 6.3 inches of snow a winter, although several winters—especially during the 1950s and 60s—have seen much more. Seattle’s official snowfall records were taken at Sea-Tac Airport from 1945 through the winter of 1995-96, and again from the winter of 2004-05 onward. Unfortunately, from 1996 to 2004, snowfall was not measured at the airport. The one-day record for snowfall at Sea-Tac is 20 inches on Jan. 13, 1950—although the city’s overall snowiest 24-hour period occurred from Feb. 1-2, 1916, when 21.5 inches was measured at the Federal Building in downtown Seattle.

The winter of 1968-69 stands as Sea-Tac's snowiest, with a whopping 67.5 inches. Of course, the legendary winter of 1949-50—which featured a 20-inch snowfall on Jan. 13, 1950—didn't do so bad either, coming in second with 63.6 inches
