Seattle is starting Sunday clear and cool, with temperatures in the mid-40s and calm conditions across the city. Skies should brighten quickly, sending afternoon temperatures near 58 degrees with no rain expected. It is a friendly window for a walk, brunch or one last outdoor errand before the clouds regroup.
Sunshine Holds Through Sunday
Sunday will be mostly sunny, with winds at Seattle-Tacoma International Airport northeast in the morning, then shifting to northwest in the afternoon. A little patchy fog may linger in nearby low-lying areas early, but the National Weather Service expects it to fade by late morning. No watches, warnings or advisories are in effect for Seattle.
Clouds Move In Monday
Sunday night will have lows in the mid-30s to mid-40s. Monday stays gray but mild, topping out near 59 degrees with light winds, while Tuesday brings mostly sunny skies and another high near 59. Wednesday looks like the warmest day of the stretch, with sunshine and a high near 63.
Rain Waits Until Thursday
A chance of showers is in the forecast Thursday, with highs in the mid- to upper 50s, according to the National Weather Service. Friday and Saturday carry only slight rain chances, with highs in the upper 50s. The broader setup remains unusually dry for October; the weather service says Sea-Tac has recorded just 0.08 inches of rain so far this month.
Cool Mornings Stay In The Forecast
Overnight lows will range from the mid-30s to mid-40s through the week, with the coldest locations possibly near freezing Tuesday and Wednesday, so a jacket will remain useful after sunset even when afternoons turn comfortable. For Sunday, the practical plan is simple: dress for a chilly start, then enjoy the sunshine before Seattle's cloud cover makes its return.
