Will School Be Closed in Seattle, Washington?
Real-time probability that schools in Seattle, Washington will be cancelled tomorrow, based on live forecast data and local closure thresholds.
It's 67°F — no snow day expected.
Typical closure threshold
1–3 inches of accumulation (rare event)
Seattle rarely sees snow at all — but when it does, it closes schools quickly. Pacific-northwest cities have minimal winter infrastructure because snow events happen maybe once or twice per year. Add the region's steep terrain and the mild-but-near-freezing temperatures (which produce ice rather than plowable snow), and even an inch of accumulation can shut down an entire district.
Why Seattle closes for small events
Seattle's hilly topography — unusual for a west-coast US city — is the biggest factor. Ice on steep urban streets makes school-bus routes impassable even when downtown and freeway conditions are fine. Parents living above 500 feet of elevation face completely different conditions than those closer to sea level, which complicates the district-wide decision.
The region's climatological "sweet spot" for winter misery is 32–35°F with precipitation — a range where rain, sleet, snow, and ice are all possible in the same storm. Forecasters struggle to pin down the precipitation type, and districts err on the side of closure when the overnight temperature is forecast anywhere near freezing with moisture incoming.
Typical winter in Seattle
Seattle averages 5 inches of snow per year — most years, one or two small events. Schools typically close 0–2 times per winter, but when they close it's usually multiple consecutive days while conditions thaw.
- Seasonal snowfall: 5 inches
- Primary closure trigger: 1–2 inches + overnight freezing temperatures
- Hilly terrain amplifies the impact of even small accumulations
- Ice events are more common than pure snow events
