Indiana's Lake Michigan shoreline in the coho-to-Chinook window for May
Direct buoy and gauge readings for the Indiana shoreline are unavailable today, but the broader Lake Michigan picture is encouraging heading into mid-May. The WI DNR Lake Michigan Fishing Report documented a record coho salmon harvest of more than 210,000 fish in 2024, along with 160,000-plus Chinook — the highest Chinook count since 2012. Both figures reflect robust alewife forage classes that drove exceptional stocked-fish survival across the entire lake. IL/IN Sea Grant notes spring is buoy deployment season for its three nearshore Lake Michigan monitoring stations, which will sharpen water-temperature tracking as conditions evolve. For Indiana shoreline anglers, May is the classic coho-to-Chinook handoff: silver salmon runs typically taper through the second half of the month as king salmon begin building offshore before their midsummer nearshore push. Yellow perch action in harbors and nearshore structure generally picks up as surface temps climb. Steelhead stragglers may still be accessible in tributary streams for another week or two.

What's Next
No live buoy data is available for the Indiana nearshore today. Seasonal patterns for Lake Michigan's southern basin in mid-May suggest surface water temperatures somewhere in the upper-30s to mid-40s°F range — cold enough to keep remaining coho salmon somewhat active near pier heads and river mouths, while also beginning to concentrate baitfish schools that attract Chinook from deeper offshore staging areas.
Watch the IL/IN Sea Grant buoy network as it comes back online this spring. The program's three nearshore Lake Michigan stations will provide the most reliable temperature-curve data available to local anglers — a consistent rise through the mid-40s toward 50°F is historically the trigger that shifts the productive window from coho to Chinook on the Indiana shoreline.
Looking ahead, if the lake follows its typical warming curve over the coming weeks, Chinook will start responding to offshore trolling presentations — generally in 60–100 feet of water — as alewife schools migrate into those zones. Given the WI DNR Lake Michigan Fishing Report's confirmation of strong alewife classes underpinning the 2024 record harvest, bait availability should remain solid heading into 2026, which historically correlates with better catch rates. Standard spoon and fly-and-dodger setups behind in-line boards or jet divers are worth testing as fish suspend in the upper water column.
Yellow perch in harbor structures and breakwall areas typically become more consistent through late May as surface temps climb. Light jig-and-minnow rigs worked along bottom in 10–25 feet of water are the standard go-to approach for this fishery.
For timing: early morning has historically been the most productive window for salmon, particularly in the two hours bracketing sunrise. Tonight's waning crescent moon phase generally correlates with pre-dawn feeding activity — a 5 a.m. launch is worth considering if the forecast cooperates. Lake Michigan's southern basin can generate dangerous wave heights quickly when wind shifts; always check NOAA marine forecasts before heading offshore. Scout Thursday–Friday weather windows to lock in any favorable weekend run.
Context
May on the Indiana shoreline of Lake Michigan is historically the bridge month between the spring salmon run and the summer offshore fishery — and knowing where you are in that transition is key to targeting the right species.
Coho salmon are the iconic early spring draw at Indiana's southern Lake Michigan piers and river mouths, with runs typically peaking from late February through April. The bite usually tapers noticeably in the second half of May as water temperatures rise. Anglers targeting coho in mid-May are fishing a closing window; fish are still present, but numbers and average size typically decline week-over-week from here.
Chinook salmon follow a different trajectory. Through May, kings are generally holding in offshore staging areas and haven't yet committed to their nearshore midsummer push — that transition accelerates through June as surface temps warm and baitfish concentrate along the shoreline structure.
The 2024 season, documented in the WI DNR Lake Michigan Fishing Report, serves as an encouraging recent benchmark: record coho (210,000-plus) and Chinook (160,000-plus) harvests — driven by strong alewife forage classes — produced some of the best Lake Michigan salmon fishing in recent memory. Whether 2026 tracks similarly will depend on stocking outcomes and alewife winter survival, data that typically won't be clear until mid-season reports emerge.
No Indiana-specific charter, tackle shop, or state agency report for this shoreline segment appears in today's intel feeds, so a direct year-over-year comparison isn't possible from available sources. The honest read: the lake-wide context from the WI DNR points to a healthy salmon population entering 2026, but local conditions at the Indiana shoreline specifically require on-the-ground intelligence — pier regulars and harbor bait shops will have the freshest read on whether coho are still showing or the bite has already shifted to early perch and offshore kings.
