Seattle is starting to settle in to its familiar fall weather pattern of warm, sunny days and clear cool nights- a perfect time to try scuba diving in the Northwest and explore the best dive sites in Seattle and Puget Sound. Water temperatures remain relatively warm while visibility improves to some of the best of the year. Fall also brings with it stunning bioluminescence, with millions of microscopic invertebrates creating a glow in Puget Sound water during night dives.

Both Steller sea lions and California sea lions have returned from their breeding rookeries in Alaska and California to join our year-round Harbor seal population to rest on Seattle beaches. As always, Seattle Dive Tours works closely with Seal Sitters Marine Mammal Stranding Network to identify and protect resting seal pups.

Underwater, fish and invertebrates look even more stunning in the clear, cool water. Copper rockfish and Brown rockfish are plentiful, while Nudibranchs such as White-lined Dirona, Opalescent Nudibranch, and Yellow margin Dorid are all reaching their largest sizes of the year, plus our own Puget Sound Giant Pacific octopus is usually around for a viewing by our scuba divers.

Our PADI professional dive guides will be at the Northwest’s best dive sites in Seattle this fall to show both visiting and local divers the amazing beauty of Puget Sound.
