Average Snowfall in Seattle: What to Expect
Seattle, Washington, isn’t typically known for massive snowstorms, but it does experience snowfall. On average, Seattle receives about 6.6 inches of snow per year. However, this number can vary significantly from year to year, with some years seeing virtually no snow and others experiencing substantial accumulations.
Annual Snowfall Averages
The 6.6-inch average masks the inconsistency of Seattle’s snowfall. Some years might bring a single dusting that melts within hours, while others deliver multiple significant snow events. It’s important to consider that the city’s location, nestled between Puget Sound and the Cascade Mountains, creates microclimates that influence precipitation patterns.
When Does Seattle Typically See Snow?
The most likely months for snowfall in Seattle are December, January, and February. While snow can occur as early as November or as late as March, these three months are the peak period. Even during these months, snow is not guaranteed, and rain is far more common.
Factors Affecting Snowfall in Seattle
Several factors determine whether Seattle receives snow. Cold air from the Fraser Valley in British Columbia can push southward, colliding with moist air from the Pacific Ocean. If the temperature is cold enough – typically at or below freezing (32°F or 0°C) – precipitation will fall as snow. The elevation also plays a role; higher areas in and around Seattle tend to receive more snow than lower-lying areas.
Historical Snowfall Records
Seattle has experienced some notable snowstorms in its history. Records available on sites like Wikipedia’s Climate of Seattle page offer insights into past snowfall events and trends. These records highlight the variability of snowfall from year to year, showing that occasional heavy snowfalls are possible despite the city’s relatively mild climate.
Preparing for Snow in Seattle
While Seattle may not be a snowy city on average, residents should be prepared for the possibility of snow, especially during the winter months. This includes having appropriate clothing, ensuring vehicles are equipped for winter driving conditions (if necessary), and having a plan for potential disruptions to transportation.
