Weather for Seattle WA: What Most People Get Wrong

You’ve heard the jokes. Everyone thinks if you move to the Pacific Northwest, you’re basically committing to living inside a Tupperware container filled with mist for nine months a year. Honestly, the reputation for weather for seattle wa is a bit of a local myth we let people believe just so they won't all move here at once.

The reality? It’s complicated.

Right now, as of Thursday night, January 15, 2026, it’s actually a pretty crisp, clear night out there. The temperature is sitting at exactly 48°F, though with a 9 mph wind coming off the north, it feels more like 45°F. Humidity is high at 81%, which is classic Seattle—that damp air that clings to your wool coat. But there’s zero chance of rain tonight.

The Big Dark and the "Dry" 2025

We just came off a year that would surprise the "Rain City" haters. In 2025, Seattle-Tacoma International Airport recorded only 33.05 inches of rain. That’s nearly six inches below the annual average of 39.34 inches. It was the third year in a row we finished in a deficit.

Even more wild? We only had 132 days of measurable rain in 2025. Usually, we expect about 157. That’s nearly a full month of "missing" rain. Dog walkers were thrilled; the local ferns, maybe not so much.

But don't let the low totals fool you. We are currently in what locals call "The Big Dark." It’s that stretch from November to February where the sun becomes a rare celebrity sighting. Even when it’s not pouring, it’s "Seattle Mist"—that fine, pervasive drizzle that makes an umbrella feel useless and a high-quality Gore-Tex jacket feel like a religious requirement.

That Weird Thing Called the Convergence Zone

If you’re driving north on I-5, you might experience one of the most bizarre meteorological phenomena in the country: the Puget Sound Convergence Zone.

Basically, the air comes off the Pacific, hits the Olympic Mountains, and splits. One half goes north, the other south. When they meet on the other side—usually somewhere between North Seattle and Everett—they slam back together and get pushed upward.

Boom. Instant rainstorm.

You can be standing in total sunshine in downtown Seattle, look north, and see a wall of black clouds dumping rain on Shoreline or Edmonds. It’s why your weather app might say "sunny" while your friend ten miles away is looking for an ark.

What the Next Week Looks Like

If you're planning a trip or just trying to figure out if you can finally wash the car, the forecast for the rest of January 2026 looks surprisingly decent.

Tomorrow, Friday the 16th, is going to be a "Blue Friday" in more ways than one. It’ll be sunny with a high of 51°F and a low of 38°F. That sunny trend actually holds through the weekend. Saturday and Sunday are looking clear and bright, though Sunday night stays chilly at 37°F.

Things get a little interesting early next week. By Monday, January 19, we might see some white stuff. There’s a 10% chance of snow Monday night, continuing into Tuesday morning. Don't panic; in Seattle, a quarter-inch of snow is enough to shut down the schools and send everyone to the grocery store to buy all the bananas and kale.

By Wednesday, January 21, the "Dark Wet" returns with light rain and highs back in the upper 40s.

Survival Tips for the Emerald City

If you’re living here or just visiting, forget the umbrella. Locals don't use them; the wind just breaks them anyway. Invest in a hooded shell.

Also, watch out for the "Fakeout Sunbreak." This is when the clouds part for exactly fifteen minutes, you take your coat off, and then the sky immediately slams shut and drenches you.

Actionable Steps for Navigating Seattle Weather:

  1. Layers are everything: The temperature might only vary by 10 degrees, but the moisture makes it feel wildly different. A base layer, a fleece, and a waterproof shell are the "Seattle Tuxedo."
  2. Vitamin D is non-negotiable: During The Big Dark, most of us are basically ghosts. Supplement or get a light therapy lamp; your brain will thank you by February.
  3. Check the "Sea-Tac" vs. "Seattle" divide: Remember that official weather is measured at the airport, which is south of the city. If you’re in Ballard or University District, you’re often 2-3 degrees cooler than the "official" temp.
  4. Embrace the cozy: When the rain hits next Wednesday, do what we do. Find a coffee shop with a fireplace, grab a latte, and stop checking the radar. It’s going to be gray for a while—might as well enjoy it.
