The best fall pike fly fishing happens as a northern lake cools through the 50s and into the 40s, when the biggest pike move onto the last green weed edges next to deep water and feed harder than they have since spring. A pike’s preferred temperature drops as the fish grows, so the shallow weed zone that ran too warm for trophies all summer finally cools into their range about the time the leaves turn. Find green weeds against deep water, fish them with big streamers on a wire bite tippet, and time the trip to miss fall turnover.
When and Where Fall Pike Move as Water Cools
Fall pike location tracks water temperature more than the calendar. With the surface still in the 60s, big pike hold on the tops and outer edges of main-lake weed flats and will chase a fast-moving fly. As the water falls through about 50°F, they slide to the deep outer edge of the weedline where it meets open water: points, inside corners, and spots where weeds meet rock. Down in the 40s, the shallow weeds die back and both bait and pike concentrate on the last green beds. Cabbage and coontail hold their oxygen and their baitfish longest, so a green bed standing out against the brown is where the pike stack up.
The useful temperature range is roughly 50–65°F, with the most active feeding around 55–62°F. Above about 68°F, twenty-pound fish rarely commit; near freezing just before ice-up, they slow down and conserve energy. The aggressive window is the cool-down through the 50s and 40s, and the coldest water of the year fishes slower.
One event to plan around is fall turnover, when cooling surface water sinks and mixes the lake to a uniform temperature. During the mix, oxygen is drawn down and consumed, fish scatter, and the bite can go flat for days to a couple of weeks, worst on small lakes. The water turns off-color and sometimes smells faintly of sulfur. Turnover comes as early as September in the far north and later farther south, so the strong fall fishing usually falls before it starts or after the lake settles back cold.
Cisco Lakes: When Big Pike Leave the Weeds
On deep, clear Canadian Shield lakes and other waters that hold cisco (also called tullibee or lake herring), the biggest fall pike leave the weeds and forage in open water more like a lake trout. Cisco carry about twice the calories by weight of a perch or a sucker, and in late fall, often mid-to-late November, they run onto rocky shoals in 1–10 feet of water to spawn under low light. That predator bite switches on as the water hits the high 40s and stays good toward 40°F. On these lakes, a rock shoal near deep water at dusk usually out-fishes the best weed bed, and a big pale silver baitfish fly matches what the pike are eating.
Gear and Flies for Fall Pike
A fast-action 9-foot 8-weight is the all-around fall pike rod, with a 7-weight for smaller water and a 9 or 10 for the largest flies. Keep the leader short and heavy: a 25–40 lb mono or fluorocarbon butt down to about a foot of 20–35 lb wire bite tippet. The wire is what stops a pike’s teeth; heavy fluorocarbon is an option in clear water for its abrasion resistance, not for stealth, since pike are rarely leader-shy.
Match the line to the water temperature: floating for shallow flats and topwater above 50°F, an intermediate with a clear tip along the weed edges, and a sink-tip once the fish move deep or out to the cisco shoals. Fish 4–10 inch streamers on 1/0–4/0 hooks: rabbit-strip patterns like Barry Reynolds’s Bunny Fly that pulse on the pause, Dahlberg Divers and poppers early, and big pale baitfish flies for the late cisco bite. Run bright red, chartreuse, orange, and white in stained or low-light water; go natural silver and white when it’s clear.
Set the hook with a hard strip, not the rod: lifting the rod pulls the fly from a pike’s bony mouth. Slow the retrieve and lengthen the pauses as the water cools, and finish every cast with a boatside figure-eight, because a fall pike will often follow the fly to the boat before it eats.
Fall gives you the longest, most patternable shot at a genuine trophy pike all year, and most of the best of it is a drive-to fishery rather than a remote fly-in. Watch the water temperature, find the last green weeds against deep water, and keep those old fish wet and quick to release.
FAQ
What water temperature is best for fall pike fishing?
Roughly 50–65°F, with the most active feeding around 55–62°F. Big pike rarely commit above about 68°F, and they slow down again as the water nears freezing right before ice-up. The aggressive stretch is the cool-down through the 50s and 40s.
Is fall or spring better for trophy pike?
Fall is the most dependable and longest trophy window, running six to eight weeks with healthy, hard-fighting fish. Spring pre-spawn produces the single heaviest fish of the year, when females are full of eggs, but that window is shorter and more weather-dependent.
Do you need a wire leader for pike on the fly?
Yes, for bite protection you want about 12 inches of 20–35 lb wire bite tippet at the end of a short, heavy leader. A pike’s teeth cut through mono and light fluorocarbon. Heavy 40–80 lb fluorocarbon is an option in clear water, but wire is the reliable insurance against a bite-off.
What flies work best for fall pike?
Big streamers 4–10 inches long on 1/0–4/0 hooks. Rabbit-strip flies like the Bunny Fly pulse when paused for cold-water fishing, Dahlberg Divers and poppers cover early-fall topwater, and pale silver baitfish flies match spawning cisco late in the fall. Use bright colors in stained water and natural tones in clear.
What is lake turnover and how does it affect pike fishing?
Turnover is when a lake’s cooling surface water sinks in fall and mixes the whole lake to one temperature. It temporarily pulls oxygen down, scatters fish, and can flatten the bite for days to a couple of weeks, especially on small lakes. Fish before it starts or after the lake restabilizes cold.
