Seattle is starting Saturday under a gray marine layer, but the clouds should loosen by afternoon as temperatures climb from around 61°F at daybreak to a high near 79°F. Boeing Field was reporting cloudy skies early Saturday, with visibility around 10 miles and a southwest breeze near 21 mph. Rain is unlikely in the city, with only a 3% chance through the day.
Clouds Fade As Saturday Warms Up
The National Weather Service Seattle expects the marine layer to linger into late morning before gradually breaking up. Saturday afternoon should turn partly to mostly sunny, with much lighter southwest winds and temperatures in the upper 70s. The city’s forecast is quiet, although thunderstorms remain possible in the Cascades Saturday afternoon and evening.
Mountain Storms And Strait Winds Need Attention
Thunderstorm chances are higher along the Cascade crest than in Seattle, where the chance of rain remains minimal. That could mean a comfortable day in town while mountain hikers and drivers face a more changeable setup, along with elevated fire-weather concerns in the Cascades.
Boaters in the Strait of Juan de Fuca should note a Small Craft Advisory from 2 p.m. Saturday through 5 a.m. Sunday, according to the National Weather Service. The advisory does not cover Seattle’s usual city plans, but it matters for anyone heading onto the Strait, where afternoon and evening winds can turn choppy.
A Mild Stretch Runs Into Next Week
Sunday stays mostly cloudy with a high near 79°F and a low around 58°F, followed by a mostly sunny Monday near 80°F. Tuesday through Friday look cooler but still dry and comfortable, with highs from about 75°F to 77°F and overnight lows in the upper 50s.
The forecast keeps rain chances at 5% or less through Thursday and only 9% Friday. Morning clouds and afternoon clearing remain the main theme, giving Seattle a familiar marine-layer routine without much wet-weather drama.
