June, July & August in the San Juan Islands
Summer fun seems endless in the islands, from whale watching, beach hiking, fresh seafood, camping and more
What's the weather like in the San Juans in the summer?
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.
Tips for getting here in summer
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!
