Seattle is waking to cloudy skies and temperatures around 59°F Sunday, but the gray lid should lift as the day goes on. Mostly sunny skies are expected by afternoon, with a high near 70°F and only a small chance of rain.
Afternoon Sun, Then A Chilly Night
Clouds should thin through the morning before west winds pick up slightly, reaching 3 to 8 mph. Sunday night turns mostly clear, with temperatures dipping to around 54°F — cool enough for an extra layer if you are staying out late.
Seattle Warms Quickly Monday Through Wednesday
The sunny stretch strengthens Monday, when Seattle is forecast to reach 75°F. Tuesday climbs to about 83°F, followed by a warmer Wednesday near 86°F, with dry conditions and light northerly winds throughout the period.
Smoke And Heat Become The Midweek Story
The National Weather Service Seattle says northerly flow could bring more smoke into the interior, especially Tuesday and Wednesday. Moderate heat risk is expected for much of the region, while parts of the South Puget Sound could face a higher level of heat risk, so midday outdoor plans may be more comfortable earlier or later in the day.
Cooler, Cleaner Pattern Returns Late Week
Thursday stays sunny with a high near 83°F, then temperatures ease to around 80°F Friday and 76°F Saturday. Increasing onshore flow late in the week should help push low-level smoke away and bring back more typical early-August conditions.
Small Craft Advisories Cover Some Waters
Boaters should note that Small Craft Advisories are in effect from late Sunday afternoon into early Monday for parts of the Strait of Juan de Fuca and the outer coastal waters. No watches or warnings are posted for land areas in Washington.
