Tench are seen as a summer fish, and there is a reason for that. Warm water, misty dawns, bubbles over a raked spot in June. That is the postcard. But the postcard misses something, which is that autumn tench are the biggest and heaviest tench you are likely to catch all year, and hardly anyone fishes for them.
The window is real but it is short
Tench feed strongly into September and often through October, then shut down hard. They are one of the first coarse species to become genuinely difficult once the water gets properly cold, and by late November on most waters you are wasting your time.
That makes autumn tench a species you plan around rather than drift into. If you want them, go now rather than in a month.
Where they move to
Summer tench are shallow water fish. They sit over gravel, in the weed, and in the margins where the water warms first. As the weed dies back and the water cools, they follow the same pattern as most stillwater species and move deeper.
What I look for in autumn is a clean area on the bottom in slightly deeper water, ideally next to whatever weed is still standing. The transition between dying weed and clean bottom is where I would put my first bait every time.
They also go quieter. Summer tench give themselves away with bubbles and rolling fish. Autumn tench often do not, which means you are fishing on watercraft and memory rather than on signs.
Feeding: less than summer, more concentrated
The heavy particle approach that works in June is too much for October. A big bed of hemp and corn in cold water can sit there untouched and turn the swim sour.
I go tighter and richer instead. A small amount of groundbait with chopped worm and caster, or a modest scattering of pellets around the hookbait. Enough to give them a reason to stop, not enough to fill them up or to sit rotting.
Baits that keep working
Worm is the standout autumn tench bait for me and I would not fish for them without a tub of lobworms. Chopped worm in the feed and a whole one or a big section on the hook.
Corn still works and it is visible in coloured autumn water. Maggots work but bring more nuisance fish. A small boilie or a wafter keeps the smaller stuff off and will pick out a bigger fish, which suits the time of year.
Tackle and presentation
Nothing exotic. A helicopter rig or a simple running lead with a short hooklength, hooks in the 12 to 10 range, and enough line strength to deal with fish that will run for weed the second they feel resistance.
The one adjustment I make for autumn is a slightly longer hooklength than I would use in summer. Colder fish take a bait more tentatively and a bit of slack lets them get it properly rather than feeling the lead immediately.
Timing within the day
The dawn bite that dominates summer tench fishing weakens in autumn. The water is coldest at first light and the fish are slower for it. What replaces it is a mid-morning to early afternoon window, once the sun has been on the water for a few hours and lifted the temperature a degree or two.
That is a much more civilised way to fish and it is genuinely more productive from late September onwards.
Do not write off a mild spell
Tench respond to warm weather more obviously than most species. A run of mild days in late October, particularly with a south westerly, can switch a water back on when you had written it off for the year. If you get that forecast, drop everything and go.
A realistic autumn tench plan
Pick a water you know holds them and where you have caught in summer. Find the deeper water adjacent to your summer spot. Feed lightly, fish two rods on the same area, and give it from mid-morning to mid-afternoon. Take worms. Expect fewer bites than you would get in June and expect the fish that do come to be considerably bigger.
Dan Whitfield started fishing aged seven on the canal at the end of his road and never really stopped. He spent his twenties and thirties on the match circuit – club level rather than national – before deciding he’d rather catch one decent fish than a net of small ones.
These days he mostly fishes the River Trent for barbel (personal best 14lb 2oz), the Oxford Canal for roach and skimmers in winter, and the occasional gravel pit when tench are spawning and the surface fishing is too good to miss. He’s a former club secretary and still helps with junior coaching at his local angling club in Nottingham.
At The River Bend, Dan writes the coarse species guides, river fishing technique articles, and the match and pole content.
