Yes, it does snow in Olympia, Washington, but the events are typically infrequent, light, and short-lived. Situated at the southern tip of the Puget Sound, the city’s climate is dominated by a strong maritime influence from the Pacific Ocean, which results in mild, wet winters rather than cold, snowy ones. This influence leads to high annual rainfall and moderate temperatures throughout the year. The occasional snowfall is a notable winter event, often leading to a temporary halt of normal activities.
Average Snowfall and Frequency
The average annual snowfall in Olympia is low, generally falling between 6 and 10 inches per year, which is significantly less than the national average. This modest total is typically spread out over only a few days during the winter season. Snowfall is most likely to occur between late December and early February, with February often registering as the snowiest month. Measurable snow rarely remains on the ground for more than a few days before mild temperatures and rain cause it to melt.
Local Weather Influences
Olympia’s proximity to the Pacific Ocean is the primary factor limiting significant snowfall, as maritime air keeps winter temperatures above freezing for the majority of the season. Although the region receives substantial winter precipitation, it usually arrives as rain because the air is not cold enough to produce snow at sea level. True snowfall requires a rare weather pattern known as a cold air intrusion. This event occurs when frigid air from the interior of Canada, often channeled through the Fraser River Valley, pushes south and settles over the Puget Sound basin. When this cold, dry air meets a moisture-laden system moving in from the Pacific, the ingredients for snow finally align over the city.
Practical Impact of Snow Events
Because snowfall is an uncommon event, even small accumulations can cause widespread disruption. Local infrastructure is not equipped with the extensive snow-removal fleets found in colder climates, meaning that plowing and de-icing operations are limited. A few inches of snow can quickly render roads slick and impassable, particularly on the area’s many hills and side streets. This immediately affects daily life, often resulting in school closures, delays to public transit, and widespread traffic accidents. Residents must be prepared for temporary power outages and should have emergency supplies, since the region is not accustomed to extended winter conditions, and many drivers are unfamiliar with navigating in snow and ice.
