In December Seattle’s weather is generally wet and gray. December is firmly in Seattle’s rainy season and is the third rainiest month on average with 5.72 inches of rain. Days average just 1.7 hours total of rain. Part of that is due to Seattle’s northerly latitude.

The reason Seattle’s temperature is so mild relative to its location is the moderating factor of being near several bodies of water.

If you’re traveling to Seattle in December and are prepared for limited sunshine and a majority of days being drizzly, what are some activities to enjoy during the month? Here are a few of our favorites:

  • Shopping: Pike Place Market is still buzzing during the month of December and you can walk through the majority of the market in covered areas. If you want to cross the bridge over to Bellevue, you can shop at Bellevue Square, which is the region’s largest enclosed mall. During the holidays it hosts a nightly parade called “Snowflake Lane” that’s quickly becoming a local holiday tradition.
  • Museums: Seattle is full of museums that range from the Museum of Pop Culture, to the Pacific Science Center, to more under-the-radar options like the Seattle Pinball Museum. Most of these museums are either downtown or a short trip away, and can be a perfect indoor activity if the weather outside is frightful.
  • Activities: The holidays mean it’s Nutcracker season at the Pacific Northwest Ballet. Beyond the ballet, winter sports are still in full swing in December with options like the Seattle Kraken or Seattle Seahawks games.
  • Landmarks: The Amazon Spheres open up every other Saturday for tours (read our full guide here), and are a great climate-controlled activity downtown. If the weather is accommodating and you catch a sunny day, a trip to the Space Needle can provide gorgeous views across the region.
