Spring Chinook On the Move at Oregon's Columbia Mouth

What's Biting

What's Next

Over the next two to three days, the offshore breeze running at 7–9 m/s is characteristic of Oregon's late-spring wind pattern and should allow workable windows on calmer mornings. Your best shots at manageable seas will be early, before the afternoon sea breeze fills in. The 4.6-foot swell at buoy 46002 will keep bar crossings at the Columbia mouth tricky — time your exit and return on the flood or early ebb and monitor the local bar forecast before departing.

With water temps steady at 57°F, spring Chinook conditions look favorable to hold through at least the coming weekend. Per Saltwater Sportsman, the Buoy 10 zone near Astoria and Warrenton is drawing concentrated effort. If pressure builds at the river mouth, consider spreading upriver or working jetty edges where tidal influence still funnels fish. On the waning crescent moon, darker overnight conditions shift the prime feeding window toward midday tidal transitions rather than first light — though early morning still tends to produce for salmon on Pacific tidal fisheries.

For bottom fishing, the 4.6-foot swell is workable for boats built for offshore conditions. Rockfish typically feed most aggressively during tidal changes; plan drops around the incoming tide over nearshore reefs and structure for the best chance at quality lingcod mixed with black rockfish. Kelp edges and rocky outcrops in 40–100 feet of water are typical Oregon Coast producers this time of year.

Halibut anglers should verify current regulations before heading offshore — seasons, areas, and bag limits can shift annually. If open in your target area, sandy bottom zones adjacent to nearshore reefs in 100–300 feet of water are classic holding grounds as Pacific halibut move shallower with spring warming. A westerly wind shift that flattens the swell below 3 feet mid-week would be the signal to push the 30–40 fathom break and stack up on structure before weekend boat traffic arrives.

Context

For the Oregon Coast, 57°F offshore water in mid-May is broadly on track with seasonal norms. Spring Chinook — commonly called "springers" — are the flagship species for this window, typically staged near the Columbia River mouth from late March through early June before pushing upriver to spawning grounds. The Buoy 10 fishery near Astoria and Warrenton, highlighted by Saltwater Sportsman, is one of the most storied salmon fisheries on the Pacific Coast and routinely draws heavy boat traffic during the spring run; any week that finds an armada of river sleds at the mouth is a week the fish are showing.

Western Outdoor News — Saltwater reported this week that California coastal waters near Half Moon Bay dropped from 58°F to 54°F, dramatically improving salmon conditions to the south. Oregon's buoys holding at 57°F suggests no similar cooldown has propagated northward yet — that reading is within the normal upper band for mid-May offshore Oregon, where 52°F to 59°F is typical. If a cooling trend does push north, it would likely enhance rather than suppress salmon activity.

Coho salmon are generally on a later schedule than Chinook along the Oregon Coast — their nearshore presence typically builds from late June through September — so any coho action reported in May is considered early and opportunistic rather than a sign of a full run. Rockfish and lingcod bottom fishing tends to be reliable throughout May once early-season swell patterns moderate, and the Pacific halibut season under recent management frameworks typically opens for the Oregon Coast in spring, with harvest limits subject to annual adjustment based on stock assessments. Conditions this week are consistent with the normal May halibut window, pending current regulatory confirmation.

Overall, mid-May 2026 is shaping up as a textbook spring Chinook setup for the Oregon Coast — nothing anomalous in the data, and no excuse to leave the gear in the garage.
