When to fish Seattle
Each row is shaded against that species' own best month here, so a dark cell means a good month for that fish rather than a comparison between them.

- Chinook Salmon. Puget Sound Chinook show a resident 'blackmouth' presence through winter and early spring, a building summer run as Hood Canal, Stillaguamish, Skagit and Snohomish-bound fish stage in Area 9/10 from late June through July (peak mid-to-late July), and a secondary September pulse of Green/Duwamish-bound fall Chinook moving through Elliott Bay. Late fall through midwinter abundance dips as mature fish enter rivers before sub-adult feeders rebuild numbers.
- Coho Salmon. Coho abundance in Puget Sound builds through summer as resident 'blackmouth' coho fatten on baitfish, then peaks in late August through mid-September when mature ocean returns stage off river mouths like the Duwamish, Puyallup, and Snohomish. By mid-October most fish have pushed into freshwater, leaving the saltwater nearly empty through winter and early spring.
- Halibut. Pacific halibut migrate into Puget Sound and nearshore Washington waters from deeper offshore spawning grounds in spring, with peak biological abundance from mid-April through May. Numbers taper through summer as fish disperse, and most halibut return to deeper offshore waters by fall and winter, leaving only a residual population in inland waters.
- Lingcod. Lingcod are resident in Puget Sound year-round, so abundance never drops to zero. The clear peak occurs March–May when mature fish move onto nearshore rocky reefs to spawn and males guard egg masses, concentrating the local biomass; summer through winter shows a slow taper as fish disperse back to deeper structure.
- Dungeness Crab. Dungeness crab are resident year-round in Puget Sound, but abundance of legal-sized hard-shell males peaks in late summer (Aug–Sep) after the summer molt hardens shells and fills them out. Spring (weeks 12–18) shows the lowest catchable biomass as many crabs are soft-shelled and hollow post-molt, with a gradual recovery through summer into the fall peak.
- Black Rockfish. Black rockfish are non-migratory residents of Puget Sound rocky reefs and remain present year-round, so the curve stays broad and flat near baseline. Slight peaks in late spring through summer reflect warmer, more stable water pushing fish shallower and more concentrated on structure, with minor winter dips as fish hold deeper and less actively aggregate.
- Chum salmon. Puget Sound chum are a strongly pulsed late-fall run, essentially absent until adults stage in nearshore Seattle waters (Sound, Duwamish/Green, Piper's Creek) starting mid-October. Peak abundance hits early-to-mid November (weeks 43–44) as fish school up before pushing into rivers, then tapers sharply through December with negligible presence the rest of the year.
- Pink salmon. Pink salmon in Puget Sound run only in ODD-numbered years, so a real curve would be flat zero on even years; this shows the odd-year pattern with adults staging and pushing through Seattle-area marine waters mid-August through mid-September, peaking hard around late August to early September before they enter rivers to spawn.
- Rockfish (Aggregate). Rockfish are extremely long-lived, sedentary, structure-oriented residents of Puget Sound rocky reefs and do not migrate, so biological abundance stays essentially flat at baseline year-round. Minor variation reflects only subtle seasonal aggregation/dispersal, not stock presence, which remains constant throughout the year.
- Surfperch. Surfperch are resident year-round in Puget Sound waters, so abundance never drops to zero, but shiner and pile perch aggregate strongly in spring-summer (May-August) when they move inshore to shallow beaches and pilings to give live birth. A late-summer/early-fall secondary bump reflects post-spawn feeding and juvenile recruitment before fish disperse to deeper water in winter.
- Flounder / Sole (Flatfish). Flatfish (English sole, sand dab, starry flounder) reside in Puget Sound year-round, so abundance never hits zero. Spring spawning aggregations (Mar–Apr) and peak summer/early-fall feeding on shallow flats (Aug–Sep) drive the two broad peaks, while cold winter months push fish deeper and slow feeding for a modest low.
- Herring. Puget Sound Pacific herring are resident year-round but abundance concentrates during the late-winter/early-spring spawning aggregation, with a strong peak roughly late January through March as adults mass in nearshore eelgrass areas (e.g., Cherry Point, central Sound). A milder summer bump reflects juvenile recruitment and feeding schools, while late fall shows the seasonal low as fish disperse and forage offshore.
- Squid - Opal. Opal (market) squid in Puget Sound show a bimodal inshore migration, with a spring push (roughly April–May) and a stronger fall/early-winter run (September–November) when they aggregate around lighted piers in Elliott Bay and along the waterfront. Deep-winter and mid-summer months see lower nearshore abundance as squid stay offshore or in deeper water.
