Salmon trolling and lakefront smallmouth heat up in mid-June

What's Biting

What's Next

The new moon falling on June 14 opens a favorable feeding window through the coming weekend. New moon phases tend to intensify baitfish movement and reduce light penetration overnight, encouraging more aggressive surface and mid-column feeding in open-water predators. Plan dawn runs first, with a secondary push in the evening hours as surface temperatures cool.

With no live buoy data in hand, the precise depth of Lake Michigan's thermal structure off Chicago is unknown. Mid-June typically places the thermocline anywhere from 30 to 60 feet depending on how quickly surface temps climbed this spring. Chinook salmon will be staging along those temperature breaks. Downriggers or lead-core setups targeting the upper edge of the thermocline, rigged with spoons or stick baits in alewife-matching colors, are the proven approach at this stage of the season. The WI DNR Lake Michigan Fishing Report's documentation of a strong alewife forage base heading into recent stocking years is encouraging context for the size and health of fish in the water column this summer.

For nearshore anglers, wind-driven chop is your friend. As Tactical Bassin demonstrated for Great Lakes smallmouth conditions, a sustained southwest or northwest breeze in the 10 to 15 knot range concentrates smallmouth along Chicago's breakwalls, piers, and riprap edges as baitfish get pushed against windward structure. Work the Dark Sleeper swimbait slowly along the bottom, then follow with a lighter Spark Shad to pick off following fish.

Yellow perch scatter as summer water temperatures climb and are best targeted on deeper sand-gravel transitions away from boat traffic. Vertical jigging with small tungsten jigs tipped with wax worms in the 50 to 80-foot range gives the best mid-summer shot at a limit.

Before launching, pull the IL/IN Sea Grant's three nearshore Lake Michigan buoys for current temperature and wave height readings. Those real-time numbers are the most reliable local tool for dialing in the depth of the thermocline and assessing sea conditions in the days ahead.

Context

Mid-June marks a predictable transition on Lake Michigan's Chicago waters. The spring coho run, which peaks in April and May as fish follow warming surface currents toward the lakefront, is largely finished by this point. The calendar now favors offshore Chinook trolling and lake trout runs at depth, with nearshore smallmouth bass providing solid action along lakefront structure as surface temperatures settle into the mid-60s range.

The WI DNR Lake Michigan Fishing Report provides the most substantive available benchmark: 2024 produced a record coho salmon harvest exceeding 210,000 fish and a Chinook tally topping 160,000, the strongest Chinook numbers since 2012. The WI DNR credited improved alewife forage classes with boosting stocked-salmon survival rates significantly. Alewife populations in Lake Michigan have historically been cyclical, and a healthy forage base heading into 2025 and 2026 stocking years is a genuine positive signal for anyone targeting the offshore fishery this summer off Chicago.

For nearshore species, mid-June is typically reliable smallmouth territory along the Chicago lakefront. Breakwalls, piers, and rocky riprap hold strong concentrations of bass when surface temps are in range, with the bite generally holding through July before summer heat and growing boat pressure push fish to deeper or more offshore locations.

No current-season intel from Chicago-area charter captains or local tackle shops was available in this report cycle. For real-time conditions specific to the Chicago port, check with Illinois Lake Michigan charter operators or the IL/IN Sea Grant nearshore buoy network, as on-the-water data would meaningfully sharpen the forecast presented here.
