Summer fun seems endless in the Islands between whale and wildlife tours, kayaking, hiking, savoring island-grown meals, and relaxing by the water. July and August are the busiest months in the Islands, so be sure to plan ahead, book reservations, and follow our Leave No Trace Principles to reduce impact on the Islands’ fragile ecosystems.
Farmers' markets on Lopez, Orcas and San Juan Islands are in full swing in summer, with fresh baked goods, locally roasted coffee, farmed and foraged produce, artisan cheeses, and creations of all kinds by local artists. You can find island-grown foods at many shops and co-ops, savor gourmet meals from award-winning chefs, and sip a delicious craft beverage with a water view.
The San Juan Islands enjoy an average of 247 days with sunshine and about half the rainfall of the Seattle area, 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 mid-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, and rarely the 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.
