Salmon and steelhead in prime spring window off Sheboygan and Door County

What's Biting

What's Next

The next several days represent a solid opportunity for Lake Michigan salmon trollers running out of Sheboygan and the open Door County ports (note the Rowley's Bay access closure through May 31 per WI DNR—plan launch logistics accordingly). Mid-May is traditionally the heart of the spring Chinook and coho bite, as lake surface temperatures typically climb through the mid-40s to low-50s°F range and draw alewives into predictable depth bands along the thermal break.

Chinook (king salmon) typically suspend in the upper 30–60 feet of the water column over 80–150 feet of depth this time of year. Flasher-fly combos and spoons in chrome, green, and alewife-pattern colorways are the seasonal workhorses. Early-morning runs before wind chop builds are generally the most productive window.

Coho are more likely to run higher in the water column—sometimes within 20 feet of the surface—and respond well to faster trolling speeds with smaller spoons. With the WI DNR's 2024 harvest data pointing to strong coho year-class survival, angler expectations going into this season should be solid.

Brown trout offer a nearshore bonus for smaller-boat anglers. Working the first major depth contour with stick-baits or shallow-diving spoons during low-light windows can produce fish before afternoon wind fills in along the Door County and Sheboygan shorelines.

Steelhead remain a possibility near river mouths along the Sheboygan area shoreline through mid-May, though peak tributary runs typically wind down as lake temperatures continue to rise. Check with local bait shops for the current river-mouth activity picture before committing to that pattern.

As the month progresses toward late May, smallmouth bass will become increasingly relevant. The WI DNR has been evaluating smallmouth management in Green Bay and northern Lake Michigan—a signal of a healthy and growing population. Pre-spawn bass should be pushing onto rocky flats and points as water temps climb toward the 55–65°F range that triggers staging behavior.

The Last Quarter moon this week historically correlates with reduced midday bite intensity—front-load your time on the water at first light and stay through mid-morning. Check the National Weather Service Marine Zone forecast before departure; late-spring Lake Michigan can deliver afternoon southwest winds that build seas quickly and cut offshore trolling short. No buoy or atmospheric data was captured for this cycle—monitor local marine forecasts carefully before launching.

Context

Early May historically sits at the apex of the spring trolling window on Wisconsin's Lake Michigan shoreline. Sheboygan has long served as one of the state's most productive salmon ports, with the spring Chinook and coho bite typically peaking between late April and late May as surface temperatures climb from the low-40s toward the mid-50s°F range. Door County, with its mix of open-lake exposure and Green Bay waters, broadens the target list to include walleye in the bay and smallmouth bass along rocky structure as the season matures.

The 2024 season set a recent high watermark. The WI DNR Lake Michigan Fishing Report documented record coho harvest and the strongest Chinook showing since 2012, driven by robust alewife year-classes that boosted stocked-fish survival. That biological foundation suggests favorable conditions heading into 2026, though no real-time current-season catch data was available to confirm whether the bite is tracking early, late, or on pace with the long-term spring average.

On the management side, the WI DNR has recently held public input sessions on both whitefish total allowable catch for Lake Michigan and Green Bay, and on smallmouth bass management in Green Bay and northern Lake Michigan. The smallmouth discussions reflect how the species has grown in angler priority across the northern part of the lake—Door County's rocky, cold, clear water makes it a natural stronghold. Any changes to whitefish limits could affect on-the-water decisions for both charter and independent anglers targeting that species.

No comparative current-season data from local charters, tackle shops, or on-water monitoring sources was available for this update. Anglers planning Sheboygan or Sturgeon Bay trips should contact area marinas and bait shops directly for the freshest real-time picture before heading out.
