About Seattle

Most travelers land at Seattle-Tacoma International Airport, informally referred to as Sea-Tac by locals. The airport is about fifteen miles from downtown Seattle, so you’ll want to take advantage of the Link Light Rail or hail a taxi. Rental cars are also an option, and you can get one from Budget or Avis. Seattle is notorious for its rainy weather, and this wet state has the highest amount of precipitation in November. The temperature varies throughout the year, depending on the season. Average temperatures range from the mid-30s during the winter to the mid-70s in the summer. Visit this stormy city in the spring or summer if you want to avoid the coldest days. A common stereotype conveys Seattle as an artsy area with lots of coffee drinkers, and there actually are quite a few coffee shops and cafes scattered across Seattle. Grab a hot cup of espresso at Bakery Nouveau or stop by Molly Moon for some homemade ice cream. Head downtown to get a glimpse of the entire city from the top of the Space Needle or take the family to the Pacific Science Center to learn more about the world. Seattle has enough museums, shops, and restaurants to keep parents and kids happy.
