Seattle’s Snowy History: A Look at Record Snowfalls
Seattle, Washington, known for its evergreen forests and rainy climate, might not be the first place that comes to mind when you think of heavy snowfall. However, the city has experienced some significant snowstorms throughout its history, with record snowfalls that have impacted daily life and created memorable moments. These events, while infrequent, remind us that even the Emerald City isn’t immune to the power of winter.
Record Snowfall Events in Seattle
Seattle’s geographical location, nestled between the Puget Sound and the Cascade Mountains, contributes to its variable winter weather. While the city’s relatively low elevation helps to moderate temperatures, cold air outbreaks from the Fraser River Valley in British Columbia can occasionally plunge temperatures low enough for significant snowfall.
The all-time record for single-day snowfall in Seattle occurred on January 13, 1950, when a staggering 20.0 inches of snow blanketed the city. This event remains etched in the memories of many Seattle residents. Other notable snowstorms include those of January 1969 (15.1 inches), February 1916 (21.5 inches total for the month), and more recently, the snowstorms of December 2008 and January 2012.

Factors Influencing Snowfall in Seattle
Several factors determine whether Seattle experiences snowfall and how much accumulates. Temperature is the most critical factor; the air temperature needs to be at or below freezing for snow to form and reach the ground. However, even if the air temperature is cold enough aloft, the snow can melt as it falls through warmer air near the surface, resulting in rain or a mix of rain and snow.
Elevation also plays a role. Areas at higher elevations in the Seattle metropolitan area, such as the hills of West Seattle or Queen Anne, tend to receive more snow than lower-lying areas near sea level. This is because temperatures generally decrease with altitude.
Impact of Snowstorms on Seattle
Significant snowstorms can have a considerable impact on Seattle’s infrastructure and daily life. Transportation is often severely disrupted, with road closures, flight cancellations, and delays on public transit. Schools and businesses may close, and power outages can occur due to downed trees and power lines.
Beyond the immediate disruptions, snowstorms can also have economic consequences. Businesses may lose revenue, and the cost of snow removal and infrastructure repairs can be significant. However, snowstorms also offer opportunities for winter recreation, such as sledding, skiing, and snowboarding, which can boost tourism in nearby mountain areas.
Frequently Asked Questions
What is the average snowfall in Seattle per year?
The average annual snowfall in Seattle is around 6 inches.
What was the biggest snowstorm in Seattle history?
The largest single-day snowfall occurred on January 13, 1950, with 20 inches.
Why doesn’t Seattle get more snow?
Seattle’s proximity to the Puget Sound and the Pacific Ocean moderates temperatures, preventing prolonged periods of extreme cold. Also, warmer air melts snow into rain as it falls in lower altitude areas.
What month does Seattle get the most snow?
Historically, January and February have been the snowiest months in Seattle.
How does climate change affect snowfall in Seattle?
Climate change is expected to lead to warmer temperatures in Seattle, potentially reducing the frequency and intensity of snowstorms in the long term. Warmer temperatures also mean that any precipitation is more likely to fall as rain rather than snow.
Summary
While Seattle is not typically known for its heavy snowfall, the city has experienced notable snowstorms throughout its history. Record events like the 20-inch snowfall in 1950 highlight the potential for significant winter weather. Factors like temperature, elevation, and proximity to the Puget Sound influence snowfall in the region. While disruptive, these events also create unique winter landscapes and recreational opportunities.
