Summary (tl;dr)

"Seattle weather" is trending as the region settles into its typical late autumn and early winter patterns, characterized by a persistent forecast of rain for the coming week and cooler temperatures, contributing to a generally wet and impactful start to December.

Essential Background

The Pacific Northwest experiences a significant shift in weather patterns as autumn transitions into winter, marked by increased rainfall and often wind, influenced by systems originating over the Pacific Ocean. Historically, November brings a noticeable increase in precipitation and cooler temperatures to Seattle. Earlier in November 2025, the region was impacted by atmospheric river events that brought substantial rainfall and strong winds to western Washington and northern Oregon, with some areas experiencing river rises and flood watches.

The Full Story

As of late November 2025, Seattle is experiencing the expected onset of its wet winter season, leading to increased public interest in local weather conditions. Today, November 30th, is mostly cloudy, but forecasts indicate a return to consistent light rain starting Monday, December 1st, and continuing throughout the week. Daily high temperatures are expected to remain in the mid-40s Fahrenheit (6-9°C), with lows in the mid-30s Fahrenheit (around 3°C), bringing a chilly and damp feel to the city. While significant snowfall is not anticipated in Seattle proper, colder air in the Cascade Mountains could lead to snow at higher passes, affecting travel.

Why It Matters

The trending interest in Seattle weather reflects public concern over the persistent wet conditions and their impact on daily life and travel. The consistent rainfall contributes to slick roadways, reduced visibility, and potentially slower commutes, particularly on major highways. While major flooding is not currently a widespread concern for Seattle, the ongoing wet weather, following earlier atmospheric river events, highlights the typical challenges and necessary preparations for the Pacific Northwest's winter climate. Residents and travelers are actively seeking updates to plan for commutes and outdoor activities amidst the wet and chilly forecast.
