When to go to Seattle

Seattle is a year-round diving destination. However, to keep warm, divers are recommended to use a dry suit with thermal undergarments made for the Arctic, because the water is always quite chilly, with the annual water temperature fluctuating between 45-55F/7-13C. Visibility can range from an average of about 15ft/5m to 80-100ft/24-30m when the conditions are optimal. Normally, the water visibility is best during the winter, but the preferable time to go to Seattle for diving is sometime between late spring and early autumn.


What to see

Divers can see a multitude of small and large marine species in emerald waters near Seattle, and the most interesting among them are hooded nudibranchs, stubby squids, giant Pacific octopi, wolf eels (which are actually fish, not eels), sea lions, sharks, and seals.

Scuba diving in Seattle

The city of Seattle is located in the state of Washington, 113mi/182km south of the US-Canadian border. The city is surrounded by large bodies of water, and the city's shoreline runs along Puget Sound to the west (an estuarine system with a multitude of healthy, protected reefs), and Lake Washington to the east (a freshwater basin that has a number of well-preserved wrecks). All this makes Seattle a world-class diving destination. The main tourist attraction in the city is the Seattle Center, where tourists can visit the EMP Musium, the Space Needle, the brand-new Chihuly Garden and Glass Musium, and if divers miss any of the must-see creatures while diving, they can see them all in the Seattle Aquarium.


Most popular dive sites

The best dive spots in Seattle are located in Puget Sound, a complex body of water that stretches for approximately 100mi/161km. Here divers can visit the Edmonton Underwater Park (a marine protected area), Redondo Beach (an easy and pleasant shore dive), Alki Cove 2 (a wreck of an old fishing boat and plenty of debris and structures to explore), Keystone Jetty (a dive site for experienced divers that features a profusion of marine life) and other dive sites.
