Timing Your Trip: Climate & Seasons 

Summer

By mid-June, temperatures have started to climb across the state, and visitors can expect blue skies with limited showers during these months. In Western Washington, the Pacific Ocean offers a cooling influence, resulting in comfortably warm temperatures for much of summer. Moving inland and east of the Cascades, temperatures trend on the higher end. During July and August, cities throughout the state can see days reaching 100 degrees. 

Travel to Washington is busiest from Memorial Day through Labor Day, peaking in July and August. Summer draws millions of visitors, particularly to destinations like Seattle, Mount Rainier National Park, Olympic National Park, and Washington’s islands. While it’s a gorgeous time to soak in the wonders of the state, keep in mind the heightened visitation when trip planning and book accommodations and other reservations in advance.

Visiting in the summer? Here’s what you need to know: 

• Know before you go. Check travel alerts and weather conditions before heading out so you’re aware of any delays or closures. 
• Book accommodations, tours, and other activities in advance. 
• Make vehicle reservations for popular ferry routes, such as Anacortes to the San Juan Islands, in advance. Plan to arrive at the terminal 45-60 minutes before departure. View our Guide to Washington Ferry Routes. 
• For popular destinations, opt to visit on weekdays and/or before 7 a.m. or after 5 p.m. 
• Have a backup plan, especially if visiting Mount Rainier and Olympic national parks. If waits are long, consider exploring less congested areas of the park or similar nearby attractions. 
  • Important Note: For 2024, Mount Rainier has implemented a new timed entry reservation system during the summer months. Learn more and book a time slot here. Find more summer travel tips and ideas for alternative destinations.
  • In Olympic National Park, the most popular destinations are the Hoh Rain Forest and Hurricane Ridge. Find summer travel tips for these areas and ideas for alternative destinations. If visiting Hurricane Ridge, consider taking the Clallam Transit bus from Port Angeles. 
  • On holiday weekends (Memorial Day, Fourth of July, and Labor Day), prepare for longer wait times. Pack plenty of water and snacks and be sure to fill up your gas tank. 

Fall

Fantastic weather continues into fall, with warm September days giving way to cooler temperatures and fall colors in October that are perfect for outdoor recreation. Early fall is mostly sunny and dry. Come November, rain starts to increase, and temperatures continue to fall. 

As the summer crowds disperse, fall is a prime time for exploration. Enjoy peaceful hiking trails in the state and national parks and easier ferry travel to the islands. Trips to Wine Country and the southern portion of the state are also a wonderful way to embrace this season’s beauty.

Winter

While rain increases and temperatures drop, winter is an excellent time for winter sports and exploring all the state’s cozy restaurants and cultural offerings. Expect moody fog, great storm watching along the coast, and peak winter wonderland experiences in the Cascade Mountains and other higher elevations. Ski season kicks off in late November and usually runs through April.  

With options for outdoor thrills and tranquil moments of discovery, there’s an array of seasonal offerings to enjoy. Find resources for winter exploration:
