What’s the Best Time To Go to Seattle? A Season-by-Season Breakdown

Seattle’s food scene shifts with the seasons, from fresh Dungeness crab in the winter months to wild salmon at the height of summer. Music runs just as deep here, as the home to Jimi Hendrix and The Crocodile music club. Just outside the city, Mount Rainier hosts outdoor adventures just as varied, from alpine trails to wildflower meadows, giving visitors one more reason to build a Seattle trip.

There isn’t much the Emerald City can’t offer, but finding the best time to go to Seattle matters just as much as picking what to do once you’re there. That’s especially true given the city’s rainy weather, steep costs and occasional influxes of visitors.

You can plan around these factors yourself with the guide below, or a AAA Travel Agent can help build a trip around the season that fits what you’re after. Either way, here’s what you need to know about the best time of year to visit Seattle.

There’s no single best month for Seattle, since it comes down to what you’re chasing. A budget trip in the winter will look different from a trip planned around a major event in the summer. Pick your priority—the sunniest days, the best rates—and there’ll be a month for it.

If you can only pick one month to visit, make it September. Crowds will have thinned since the summer rush and both hotels and rental cars will be noticeably easier to book at lower prices. Seattle weather in September still holds up, too, with daytime temperatures in the low 70s and enough sun for a full day outside without August’s wildfire smoke risk.

It’s also when Seattle Center fills up over Labor Day weekend with Bumbershoot, the city’s biggest arts and music festival. Between the savings, the weather and the festival buzz, a September trip to Seattle is best for balance and getting a bit of everything.

July and August are Seattle’s best months for good weather, especially if you’re an outdoor enthusiast eager to make the most of the city’s natural splendor.

Highs sit in the mid-70s to low 80s with barely any rain, making it easy to get around town on foot and spend a full day outside without worrying about a backup plan.

July and August are also the best times to see landmarks like Mount Rainier and North Cascades National Parks, as well as the many islands dotted around Puget Sound. Trails and roads are far more likely to be open and accessible during these months.

Just know you won’t be the only one with this idea. Summer draws the largest crowds of the year, so expect busier trails and higher hotel prices.

December and January are Seattle’s cheapest months to visit, with hotel rates at their lowest and popular attractions at their quietest all year. The trade-off is the weather: steady rain and highs that rarely climb out of the 40s, so you’ll want a mix of indoor plans and warm layers.

If you’d rather not commit to winter but still want to save, the April-to-May and September-to-October shoulder seasons split the difference. Rates aren’t as low as deep winter, but you’ll get milder weather without paying peak summer prices.

May and July are Seattle’s best months for festivals. Northwest Folklife Festival takes over Seattle Center every Memorial Day weekend, drawing an estimated 250,000 visitors for free music and cultural performances from around the region.

Come July, the Seattle Art Fair brings gallery-quality work to the city. It’s also when the city’s biggest summer celebration, Seafair, kicks off, starting with the Torchlight Parade in late July. Later on, during Seafair Weekend at the end of the month, Blue Angels jets roar over Lake Washington and hydroplane boats race below on the lake at over 220 miles per hour.

Weather isn’t the only factor, but it’s helpful to know what to expect each season.

Along with the fall, spring is one of Seattle’s shoulder seasons, when the weather and the local scene are active enough to attract visitors before the crowds pack the city. The season starts cool and gray, with rainy days and temperatures in the upper 40s in early March, climbing into the mid-60s by May. But sharp Pacific winds make the air feel much colder, so you’ll want to dress in warm layers if you’re hoping for a springtime visit.

Spring is also the time for a number of Seattle-specific seasonal events, most notably flower festivals like the Skagit Valley Tulip Festival and the Seattle Cherry Blossom & Japanese Cultural Festival, both held in April. From March to April, visitors can experience the Moisture Festival, a four-week-long comedy and variety event featuring internationally renowned and local theatrical groups, cabaret acts, stand-up, burlesque and storytelling.

Seattle’s summer weather runs mild compared to much of the country, with highs typically in the mid-70s to low 80s. It’s also the driest period for the city, with rainfall plummeting to under an inch in July. This makes it easier to get around town on foot, with clear skies for views of Mount Rainier and the Olympic Mountains that are often hidden the rest of the year.

Sea breezes keep the temperatures moderate, which is great during the day but can make nights a challenge for visitors from warmer climates. Since nighttime temperatures can drop to the mid-50s, make sure you pack a few warm garments before you travel. Luckily, days stretch long, with up to 16 hours of daylight in June, so you can get all your plans done.

You won’t be the only one heading to Seattle if you plan a summer trip, though, so you’ll have to deal with heavy crowds and higher prices. But if you’re prepared for that, summer will offer plenty of chances to visit local beaches, farmers’ and craft markets, or catch a professional baseball or soccer game.

When you’re talking about a city as forested as Seattle, it should come as no surprise that fall is one of its most stunning seasons. Maple and aspen trees provide rich splashes of gold, red and purple against the deep green backdrop of the region’s evergreens. Fall temperatures range between 50 and 70°F—cool enough to explore but not yet too cold for comfort.

Fall in Seattle is also when the city’s reputation as a music hub becomes all the more obvious, as cooling temperatures drive Seattlites into venues like the Tractor Tavern and the Triple Door to soak up the local music scene’s latest offerings. Plus, many of Seattle’s most beloved events take place in the autumn, such as the local Oktoberfest and Seahawks football games at Lumen Field.

Autumn is also a major reason the city has a reputation for rain: November is the wettest month of the year, averaging around six inches of rain. On the bright side, the summer crowds clear out in September, so you can still catch some sun without the peak-season price tag. Fall offers just as much to do as summer, at a fraction of the cost.

Winter brings biting cold and plenty of wet days to Seattle. In December alone, the average high temperature is a brisk 45°F, but it can get into the 30s and below on particularly cold days. The ever-present sea breezes and lots of precipitation leave winter feeling even colder, making it most people’s least favorite time to visit.

Many of Seattle’s most accessible outdoor activities are unappealing during the winter, with high-elevation hiking and climbing routes closed for the season. Even open attractions and areas can put off visitors who don’t want to spend a day in freezing, wet weather.

That’s not to say that you should avoid Seattle in winter. In fact, if you’re prepared for the cold and come with plenty of warm clothing, it’s possible to have an excellent time between the rock-bottom prices on lodging and several must-see events.

The Earshot Jazz Festival takes up the tail end of the fall, while the Christmas Ship Festival in December and the Jet City Improv Festival in February are just two examples of the city’s cold-weather entertainment. On top of that, outdoorsy visitors can enjoy exceptional winter activities, like skiing and snowboarding.

Pack for how much Seattle’s weather shifts by season and you’ll have a great trip no matter when you visit. Here are some planning and packing tips to help your vacation go smoothly:

Three days covers the highlights comfortably: Pike Place Market, a downtown walk and a day trip like the Bainbridge Island ferry. If you’re visiting in winter, add a fourth day, since shorter daylight hours and rain tend to limit how much you can pack into each day.

September, though the answer may shift depending on your priorities. Photographers chasing Mount Rainier views often prefer July instead, when the mountain is least likely to be hidden by clouds. Travelers on a budget may opt for a winter trip instead.

Rain peaks from November through February, but Seattle actually gets less annual rainfall than New York City or Miami. It’s the number of wet days, not the total amount, that gives Seattle its rainy reputation.

Seattle changes shape depending on when you show up. You can enjoy sunny days on Puget Sound or rock-bottom rates in the dead of winter. However you time it, you’ll still get the mountain views and the cultural scene that make the trip.
