    CharacterReef dive

    Sonora Reef, off the coast of Grays Harbor County, Washington, offers a solid dive for those exploring the Pacific Northwest. While the name suggests coral, this is very much a rocky reef, shaped by the region’s dynamic currents. We’ve spotted plenty of harbor porpoise cruising by and, if you’re lucky, a gray whale might even make a distant appearance during migration. It’s a site best suited for divers comfortable with cooler water and potentially surge, where the reward is the rugged beauty of the temperate zone, not tropical colors. Keep an eye out for Chinook and coho salmon, along with the resident common seals, often curious about visitors.

    Safety Notes

    Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
