Seasonal Fishing Opportunities
Spring Fishing (March-May)
Spring marks the eagerly anticipated transition from ice fishing to open-water angling across Wisconsin. As water temperatures gradually rise from the low 40s into the 60s, fish metabolism increases and feeding activity accelerates dramatically.
What’s Hot in Spring:
- Northern Pike: Pike become increasingly active in early spring as waters warm, with peak fishing typically occurring in April and May just after spawn. Target shallow bays with emerging vegetation using large minnows or flashy spoons.
- Walleye: Late April through May offers exceptional walleye fishing as fish complete their spawning cycle and begin aggressive feeding patterns. Focus on river mouths, current breaks, and rocky points with jigs tipped with minnows or nightcrawlers.
- Crappie: Spring brings some of the year’s best crappie fishing as these popular panfish move into shallow areas for spawning. Look for them around woody structure in protected bays when water temperatures reach the mid-50s.
- Yellow Perch: Early spring (March through April) provides tremendous perch fishing opportunities as schools gather before spawning. Target deeper water adjacent to emerging weedbeds with small jigs tipped with minnows or waxworms.
The highly anticipated Wisconsin general fishing opener on May 3, 2025 creates significant excitement throughout the angling community. This date provides the first opportunity to target many popular gamefish species after the winter hiatus, and fishing pressure tends to be heavy on popular waters.
Early Season Fishing Tactics:
- Focus on shallow, warming bays where water temperatures rise fastest
- Use slower presentations as fish metabolism gradually increases
- Target north-facing shorelines that warm quicker in spring sunshine
- Pay attention to water clarity, which often diminishes during spring runoff

Summer Prime Time (June-August)
Summer represents Wisconsin’s peak fishing season, with warm water temperatures boosting fish metabolism and feeding activity across all species. Longer daylight hours provide extended fishing opportunities, though the most productive periods typically shift to early morning and evening as water temperatures reach their seasonal highs.
What’s Hot in Summer:
- Largemouth Bass: Peak activity occurs from June through August as bass establish summer patterns around weedbeds, docks, and other structure. Topwater fishing becomes particularly effective during early morning and evening hours.
- Smallmouth Bass: Summer offers prime smallmouth action, especially on rivers and deeper, rocky lakes. Target drop-offs, current breaks, and rocky structure with crawfish imitations and soft plastics.
- Muskellunge: Trophy musky hunting reaches its prime from mid-July through August. Focus efforts around weedlines, rock structures, and points using large bucktails, topwater lures, and rubber baits.
- Panfish: Consistent action for bluegill, crappie, and perch continues through summer, though fish typically move to deeper structure as water temperatures peak. Early morning and evening periods provide the best shallow water opportunities.
Wisconsin’s numerous lake types each develop their own unique summer patterns. Shallow, fertile lakes may experience dense weed growth requiring targeted approaches, while deep, clear lakes develop distinct thermoclines that concentrate fish at specific depths. Understanding these habitat differences is crucial for summer success.
Summer Fishing Strategies:
- Target deeper structure during midday heat when surface temperatures exceed 80°F
- Consider night fishing for species like walleye and musky
- Pay attention to dissolved oxygen levels, which can diminish in shallower areas during hot periods
- Locate thermoclines using electronics to find the optimal temperature range for your target species

Fall Fishing Patterns (September-November)
Fall brings cooling water temperatures and triggers feeding frenzies across multiple species as fish prepare for winter. This period offers some of the year’s best trophy opportunities, particularly for predatory species fattening up before the coldwater period.
What’s Hot in Fall:
- Muskellunge: Trophy musky action peaks from mid-September through October as fish feed aggressively before winter. Focus on deeper structure adjacent to shallow feeding areas with large rubber baits and jerkbaits.
- Walleye: Excellent walleye fishing resumes in September and continues through November. Fish begin moving from summer haunts to wintering areas, often staging near structural elements along the way.
- Brown Trout: Fall brings spectacular brown trout action, particularly in Lake Michigan tributaries as fish begin their spawning runs. September and October provide peak opportunities.
- Northern Pike: Pike activity accelerates in fall as water temperatures cool. Target weedlines and shallow bays with large minnows, spoons, and spinners.
Fall also brings specialized opportunities like the Lake Sturgeon hook-and-line season, which runs from September 6 through September 30, 2025, allowing anglers to target these prehistoric giants in select Wisconsin waters.
Fall Fishing Tactics:
- Follow baitfish migrations to find predatory gamefish
- Focus on main lake points and drop-offs
- Pay attention to falling water temperatures that trigger feeding sprees
- Be prepared for rapidly changing weather conditions

Winter Ice Fishing (December-February)
Wisconsin’s frozen lakes provide outstanding ice fishing opportunities throughout winter, with dedicated anglers braving the cold to target a variety of species through the ice. Modern ice fishing equipment, portable shelters, and electronics have revolutionized this traditional winter pursuit.
What’s Hot in Winter:
- Panfish: Bluegill, crappie, and perch provide steady action for ice anglers throughout the winter months. Look for suspended crappies over deeper basins and perch and bluegill relating to weed edges and bottom structure.
- Walleye: Decent opportunities persist, particularly during dawn and dusk periods. Focus on structural elements like reefs, points, and the edges of flats.
- Northern Pike: Fair to good pike fishing continues through the ice fishing season. Target areas near weedbeds using tip-ups baited with large minnows.
- Trout: Many stocked trout lakes offer productive winter fishing opportunities. Focus efforts near bottom structure using small jigs tipped with waxworms or minnows.
Winter also features the unique Lake Sturgeon spearing season on the Winnebago System, running from February 8 through February 23, 2025. This cherished tradition draws thousands of dedicated spearers to the ice each winter in pursuit of these ancient fish.
Wisconsin offers free fishing weekends on January 17-18, 2026, when no fishing license is required. These weekends provide perfect opportunities for newcomers to try ice fishing without investing in a license.
Ice Fishing Safety and Tactics:
- Always check ice thickness before venturing out (4+ inches for walking, 12+ inches for vehicles)
- Fish with companions when possible
- Carry ice safety equipment including picks, flotation devices, and rope
- Dress in layers and be prepared for changing weather conditions
