Seattle is waking up to a mostly cloudy Tuesday morning with a high near 64°F expected this afternoon — patchy low fog is possible near Puget Sound early, but filtered sunshine is on the way by midday. Check the Seattle weather forecast for the latest updates throughout the day.

Today’s Setup

The National Weather Service has high pressure anchored offshore, holding the classic PNW spring pattern in place: marine layer and fog near the waterfront through mid-morning, then mid-level clouds giving way to filtered afternoon sunshine. Neighborhoods like Magnolia, West Seattle, and areas near Elliott Bay may see the thickest morning clouds. Rain chances are a low 13% today, and southwest winds stay gentle around 5 mph — a comfortable, mellow Tuesday by any measure.

Best Window to Be Outside

Target roughly 1–4 PM PT for your best outdoor window. Green Lake, Gas Works Park, and the Burke-Gilman Trail should all be pleasant by midday. Tonight is also a great night for baseball: the Seattle Mariners host the Chicago White Sox at T-Mobile Park — expect low-to-mid 50s°F by game time, calm winds, and dry conditions. Solid tailgating and bleacher weather. Wear your Seattle Mariners jersey or break out the Seattle Mariners fitted cap; if you’re still hunting for seats, Get tickets on SeatGeek before they’re gone.

Allergy Alert

May pollen is in full swing across the Seattle metro, and this morning’s fog can trap tree and grass pollen at low levels near the ground. Allergy sufferers should carry an allergy relief nasal spray for outdoor time, and running a HEPA air purifier at home overnight is a smart move to cut down on the indoor pollen load while you sleep.

What to Wear or Bring

Dress in light layers — a fleece or light jacket for the morning commute that you can shed by afternoon. No umbrella needed today, but keep one tucked in your bag; it’s Seattle in May, after all.

Next Few Days

Wednesday is the standout day of the week: mostly sunny with a high near 67°F and zero rain chance — ideal for yard work, mowing, or finally getting that patio furniture set arranged on the deck. Browse outdoor gear deals if you need to stock up. Thursday pushes even warmer, with the National Weather Service forecasting highs into the upper 70s to near 80°F across the interior — one of the best days of the spring for a hike toward Mt. Rainier or a paddle on Lake Union. Get those outdoor projects done mid-week, because the weekend brings increasing onshore flow, cooler temperatures, and rising rain chances heading into early next week.

For weekend plans, the Stifel Stars on Ice show comes to Climate Pledge Arena on Saturday, May 23 — fully indoors, so whatever the weather does, the skating goes on. Find tickets on StubHub while availability lasts.

Dinner Tonight

A mild, overcast spring evening is exactly right for a warm bowl of pasta or a quick veggie stir-fry. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Upcoming Home Games
