Weather in Seattle

The weather in Seattle is informed by a temperate maritime climate characterised by rainy skies and moderate temperatures year round. The city experiences cloudy conditions for about 200 days annually, with partly cloudy skies adding another 90-plus days. Heavy rainfall is concentrated in the winter months of November, December and January, when the city receives roughly half its annual precipitation. The rest of the year is mostly dry, particularly from June to September, when summer brings short-lived warmth and clear skies.

You’ll find mild daytime temperatures throughout the year. July and August are the hottest months, with average temperatures around 75°F (24°C). Winter temperatures rarely drop below 32°F (0°C), and snowfall is uncommon. The Pacific moderates Seattle’s climate, keeping winters milder than inland areas and summers cooler than you might expect. Pack layers year round, as mornings can be cool even during summer months.

Seattle’s reputation for rain exceeds reality in terms of total precipitation – the city actually receives less rainfall annually than New York or Houston. The difference lies in frequency rather than intensity. You’ll encounter light drizzles spread across many days instead of heavy downpours.
