Summer Inspiration for the Senses

Summer weather in the San Juans

The San Juan Islands enjoy an average of 247 days with sunshine and about half the rainfall of Seattle, thanks to the "rainshadow" effect of the Olympic Mountains to the south. It's no wonder visitors are attracted to the islands year round! Summer is in full swing from late June through early September, with an average daytime temperature of 67 degrees in June and 71 in July and August. Some days can send the thermometer into the 80s, or even 90s, but usually the temperature stays pretty steady in the mid- to high-70s. Wear your shorts and sundresses, but make sure to keep a sweater or light jacket handy, especially if you go on an evening beach walk, where coastal breezes can turn evenings cool.

Summer Travel Tips

In summertime, the Washington State Ferry schedule is at its peak travel capacity. With the large number of travelers to the San Juan Islands, it is necessary to make a reservation to ensure a spot for your car. You can take a quick, 3-hour foot-ferry, the San Juan Clipper, from Seattle as well. Bike-on and walk-on passengers don't need to make a reservation, and for most interisland travel, there are no reservations required. You can also take a shuttle from Sea-Tac Airport to Anacortes. See our Getting Here page for details and suggestions about how to travel efficiently and make the most of your trip. 

Summer is a fantastic time to travel by airplane or seaplane, to take off from Seattle and see the city below transition into scattered islands and light glinting off the water. It is truly a spectacular experience!

Things to do this summer

Summer is all about outdoor fun! Paddle a kayak along the shoreline at sunset, or see orca whales, seals, sea lions, and eagles on a whale and wildlife watching tour. Each island has its own terrain for bicycling, so make sure to check out our biking pages to have a fun and safe biking trip. On San Juan Island, you can go ziplining through the trees.

Stunning views and well-groomed trails are a dream for hikers. On Orcas Island, climb to the top of Mt. Constitution in Moran State Park, Washington's 4th largest state park, then shuck an oyster at Buck Bay Shellfish Farm. On Lopez Island, explore the sandy beach at Spencer Spit State Park or hike through the woods and emerge on rocky bluffs with outlooks over the water at Shark Reef Sanctuary, then enjoy artfully prepared local food at Ursa Minor restaurant in Lopez Village.

Check out the local shops filled to the brim with art and crafts made by island artisans. The Saturday farmers' markets on Lopez, Orcas and San Juan offer a fun-filled day, with fresh baked goods, music, and locally grown, fished and foraged foods. Enjoy live music and a local art show every Friday in August at the San Juan Summer Arts Festival! Check out more San Juan Islands Experiences.
