When Was the Last Time It Snowed in Seattle?

The last measurable snowfall in Seattle occurred on February 24, 2023, when the city experienced approximately 1-2 inches of snow. While flurries have been observed since then, they haven’t accumulated to significant levels. Snowfall in Seattle is relatively infrequent and often short-lived due to the city’s mild, maritime climate.

Understanding Seattle’s Snow Climate

Seattle’s location in the Pacific Northwest results in a climate characterized by mild, wet winters. Proximity to the Pacific Ocean moderates temperatures, preventing prolonged periods of extreme cold necessary for consistent snowfall. The city’s elevation also plays a role, with higher areas generally experiencing more snow than lower-lying areas. While Seattle might not be known for its blizzards, snow events do occur, albeit sporadically.

Details on the February 2023 Snowfall

The February 2023 snowfall event brought a brief but impactful interruption to daily life in Seattle. Although the accumulation was modest compared to other parts of the country, the snow caused disruptions to transportation, school closures, and adjustments to daily routines. The city’s relatively infrequent snowfall events can sometimes lead to challenges in preparedness and response.

Factors Influencing Snowfall in Seattle

Several factors contribute to whether Seattle receives snowfall. Cold air masses from the interior of North America need to reach the Puget Sound region. Simultaneously, sufficient moisture is required, often in the form of a Pacific storm system. When these two conditions align, Seattle has a higher chance of experiencing snow. However, even with these conditions met, the temperature needs to be cold enough at ground level for the precipitation to fall as snow rather than rain.

Historical Snowfall Data and Averages

Seattle’s average annual snowfall is around 6 inches, but this varies significantly from year to year. Some years see no measurable snowfall at all, while others experience several inches of snow over multiple events.
