As we head into September, the color of salmon switches from pink to silver around Puget Sound.
The front end of the migratory coho run – also known as silvers for their shiny silvery-colored body – began to filter into the western Strait of Juan de Fuca and Puget Sound in August, and are expected to peak throughout September and early October.
Coho aren’t large – usually averaging 4 to 15 pounds, with some exceeding the 20-plus pounds – but they often put up a good tussle. Young coho spend a year in rivers and estuaries and then migrate out to the Pacific Ocean to feed and grow. They spend about 1½ years in the ocean, then return to spawn as three and four-year-old fish, generally in fall or early winter.
Puget Sound coho returns have gradually made a comeback from a downtrend that began in 2015 and 2016. This was due to negative environmental factors like drought, flooding, and warm water temperatures in their freshwater habitat as juveniles and then in the Ocean from a condition known as El Niño, when surface water becomes warmer than average.
The combined 2025 Puget Sound hatchery and wild coho forecast is 727,490 compared to 722,134 in 2024; 760,029 in 2023; 666,317 in 2022; 614,948 in 2021; and 504,604 in 2020.
Coho fill the air with enthusiasm for their leaping abilities when hooked, and unpredictable movements across the water’s surface.
A positive signal of 2025 expectations began with the good fishing for resident coho, who mainly spend their entire life feeding and growing in local waters –
caught in Marine Area 10 (Seattle and Bremerton Area) from June to early August. Many of these coho have grown since then and will join their larger migratory coho relatives during the late summer and fall marine fisheries.
Knowing when it is “go fishing time” for migrating coho in Puget Sound is to monitor catch rates in the Strait of Juan de Fuca at Marine Area 5 (Sekiu and Pillar Point) and Marine Area 6 (East Strait of Juan de Fuca).
The Marine Area 5 salmon fishery is open daily through Sept. 26 with a two salmon daily limit, plus two additional pink may be retained, and release Chinook, chum, sockeye, and wild coho. The area is then open daily for coho from Sept. 27 to Oct. 9 with a two salmon daily limit, release Chinook, chum, and sockeye.
The Marine Area 6 salmon fishery is open daily through Sept. 26 with a two salmon daily limit, plus two additional pink may be retained, and release Chinook, chum, sockeye, and wild coho. The area is then open daily for coho from Sept. 27 to Oct. 15 with a two salmon daily limit, release Chinook, chum, and sockeye.
Oftentimes, the best coho fishing in the Strait of Juan de Fuca occurs offshore in the shipping lanes, which is the main migration path. These deep-water areas are about one to 10 miles out in 200 to 500 feet of water and sometimes even deeper off the edge of the main shipping channels. Remember to stay within the U.S. side of the shipping lane. Look for tide rips and current breaks where krill and schools of baitfish attract coho, and watch for coho jumping and rolling on the surface.
In the eastern Strait of Juan de Fuca, the Dungeness Bay hatchery coho fishery is open from Oct. 1 to 31. The 2025 Dungeness River coho forecast is 13,328, down slightly from 14,305 in 2024 and 14,654 in 2023.
The Marine Area 7 (San Juan Islands) coho season is open daily through Sept. 6 with a two salmon daily limit, plus two additional pink may be retained, and release Chinook, chum, sockeye, and wild coho. The area is then open daily for coho from Sept. 7 to 30 with a two salmon daily limit, plus two additional pink may be retained, and release Chinook, chum, and sockeye. In Marine Area 7, look for coho staging along the western and southern portions of the island chain.
Coho fishing in Marine Area 8–1 (Deception Pass, Hope Island, and Skagit Bay) is open daily, Sept. 30, with a two salmon daily limit, plus two additional pink may be retained, and release Chinook and chum. Coho fishing is then open daily Oct. 1 to 12 with a daily two salmon catch limit, and release Chinook and chum.
In Marine Area 8–2 (Port Susan and Port Gardner), coho fishing is open daily through Sept. 24 with a two salmon daily limit, and release Chinook, chum, and pink. The Tulalip Bay Terminal Area Fishery has rules that differ from Marine Area 8-2. For details, check the Washington Department of Fish and Wildlife (WDFW) fishing regulations webpage at https://wdfw.wa.gov/.
In Marine Areas 8-1 and 8-2, anglers should find coho along the entire eastern side of Whidbey Island, Possession Point, off the Clinton Ferry Terminal, the Langley/Sandy Point area, Shipwreck to Mukilteo, Hat Island, Camano Head, the entire west side of Camano Island, and outside of Oak Harbor. West Beach at Deception Pass State Park, located north of Oak Harbor on Whidbey Island, provides excellent shore fishing access.
Moving further into Puget Sound, Marine Area 9 (Admiralty Inlet) is another decent fishing location for hatchery-marked coho, which is open daily through Sept. 30. It has a two salmon daily limit, plus two additional pink may be retained, and release Chinook, chum, and wild coho.
In Marine Area 9, focus your fishing time in the unmarked shipping lanes where tide rips and current breaks are commonly found. Try Midchannel Bank off Port Townsend; Point Wilson north of Port Townsend (good public shore access); east side of Marrowstone Island (some shore access); Fort Casey to Bush Point and Lagoon Point (some public shore access); Double Bluff off the west side of Whidbey Island; Point No Point (excellent public shore spot); Possession Bar; Scatchet Head; and Pilot Point.
In Marine Area 10 (Seattle and Bremerton Area), coho fishing is open daily through Sept. 30 with a two salmon daily limit, plus two additional pink may be retained, and release Chinook and chum. Fishing is also open daily from Oct. 1 to Nov. 15 with a two salmon daily limit, and release Chinook.
In Marine Area 11 (Tacoma and Vashon Island), coho fishing is open daily through Sept. 30 with a two salmon daily limit, plus two additional pink may be retained, and release chum and wild Chinook (note, the Chinook fishery may close sooner so check the WDFW fishing regulations webpage for updates. Fishing is also open daily from Oct. 1 to Nov. 15 with a two salmon daily limit, and release Chinook.
Look for coho in the deep-water shipping lanes off Jefferson Head to Kingston, Richmond Beach to Meadow Point near Shilshole Bay, Point Monroe, Shilshole Bay south to West Point, Elliott Bay, the Fauntleroy Ferry area southeast to Dolphin Point, both sides of Vashon Island, Redondo Beach to Dash Point and the Tacoma area of Commencement Bay, Browns Point, and Point Defiance Park from the Slag Pile to the Clay Banks.
Two popular events tied to the arrival of coho are the Edmonds Coho Derby on Sept. 6. For details, go to http://edmondscohoderby.com/. That will be followed by the Everett Coho Derby on Sept. 20-21. For details, go to https://everettcohoderby.com/.
Marine Area 13 (South Puget Sound) is open daily for hatchery-marked coho through Sept. 30 with a two salmon daily limit, plus two additional pink may be retained, and release chum, wild coho, and wild Chinook. Fishing remains open daily beginning Oct. 1 with a two salmon daily limit, and release chum, wild coho and wild Chinook.
In Marine Area 13, look for coho from the Narrows Bridge south to Anderson Island. The Squaxin Island area has become popular area for those targeting coho. The 2024 Squaxin Island net pens coho forecast is 59,596 up from 48,081 in 2024 and 45,417 in 2023.
If you’re looking for a Chinook and coho option try the Bellingham Bay Terminal Fishery open daily through Sept. 30 with a daily limit of four salmon.
Sinclair Inlet and Port Orchard are open daily through Sept. 30 with a three salmon daily limit, plus two additional pink may be retained, and release chum and wild Chinook. Fishing is then open daily from Oct. 1 to Nov. 15 with a two salmon daily limit, and release Chinook.
Lastly, a freshwater coho fishing option in Seattle’s backyard is Lake Washington north of the Highway 520 Bridge, which is open daily from Sept. 16 to Oct. 31 with a daily limit of four coho only, and release all other salmon species. The Lake Washington coho forecast is 28,112 up from 24,090 in 2024 and 21,554 in 2023.
In the October issue, we’ll switch gears and take a look at proposed fall and winter coastal razor clam digging opportunities.
I’ll see you on the water very soon!
