Lake Michigan Salmon Season at Full Stride as New Moon Arrives Near Chicago

What's Biting

What's Next

**The next 2–3 days** should favor anglers who can get out early. Tonight's new moon removes ambient light from the pre-dawn hours — historically one of the most reliable triggers for Lake Michigan salmon to push shallower on the thermocline and for nearshore smallmouth to become aggressive along rocky structure, breakwalls, and harbor mouths in the Chicago metro.

**For offshore salmon trollers**, mid-June is the heart of the Chinook season, and it is also when the coho bite — which ran at record levels in 2024 per the WI DNR Lake Michigan Fishing Report — can overlap with kings on the same spread. As the thermocline stabilizes through the month, fish typically suspend in the 50–90 foot depth range. Downriggers with spoons and fly-and-flasher rigs are the standard approach; run some baits in the upper 20 feet to cover coho, and probe the thermocline with deeper riggers for kings. The next two mornings (June 15–16), with low-light conditions at their peak before first light, are worth setting an early alarm.

**For nearshore anglers**, lake surface temps should be climbing toward seasonal range through mid-month, pushing smallmouth bass into shallower rocky structure. Tactical Bassin's Great Lakes smallmouth content highlights a two-bait approach as a reliable early-summer setup: a Dark Sleeper on a swinging jighead for bottom-contact in heavier conditions, paired with a more finesse-oriented Spark Shad when fish are biting short. Chicago's lakefront piers and jetties offer concentrated structure where smallmouth stage as baitfish push in, and new-moon windows can shift feeding activity noticeably at first light.

**Wind direction will be the key variable** that no current buoy data can clarify. Southwest winds push warm surface water offshore and energize the nearshore zone; northeast winds can suppress the bite by pulling colder, deeper water toward shore. Check local marine forecasts — including the IL/IN Sea Grant buoy dashboard when readings return — before heading out. Either way, plan around the first 90 minutes of daylight for the best new-moon action window this week.

Context

Mid-June on Lake Michigan near Chicago is traditionally the transition point between spring and summer salmon patterns. Chinook kings are the headline target at this stage of the season, and the broad-lake population picture heading into 2026 is encouraging: per the WI DNR Lake Michigan Fishing Report, 2024 produced more than 160,000 Chinook harvested — the best tally since 2012 — along with a record coho count exceeding 210,000 fish. The WI DNR attributed both results to robust alewife forage year-classes in recent years, a supply of prey fish that the Illinois side of the lake shares equally. Healthy forage means better stocked-fish survival, which directly benefits Chicago-area charter and shore anglers targeting the same migratory run.

Illinois-Indiana Sea Grant operates three nearshore buoys in Lake Michigan that anglers and mariners have come to rely on for real-time temperature and wave data, describing the network as a popular public resource. No readings were available in this cycle, so it is not possible to confirm whether water temps are running ahead of or behind the seasonal norm.

Typically, mid-June Chicago-area surface temperatures approach the upper 50s to low 60s°F, with the thermocline beginning to set up between 30 and 50 feet and deepening as July approaches. If this year's warming is tracking on schedule, Chinook should hold on the thermocline edge through the remainder of June before pushing deeper when surface temps climb further. Smallmouth bass follow a complementary calendar, staging on rocky nearshore structure in June before mid-summer heat gradually slides them into slightly deeper water. There is no current-season Chicago-area comparative data in this cycle; treat the seasonal baseline above as the best available reference rather than a confirmed readout.
