"They're feeding up for winter." You'll hear it at every ramp this month, and it's wrong on two counts. A bass has no idea winter is coming, and it isn't eating more than it did in summer. It eats what the water temperature lets it eat.
Picture two guys on the same November Saturday. One is in Minnesota, holding a drop shot dead still in 28 feet of 44-degree water. The other is in Alabama, ripping a lipless crankbait across a three-foot flat while shad spray out in front of him. They're both doing the right thing.
Late autumn doesn't arrive equally. The date is the same in both places, but the water temperature isn't, and that's the only part the fish care about.
A bass is only as warm as the water it's in
Fish physiologists have a rough rule that metabolism doubles or triples with every 18°F rise in water temperature. It's a general fish figure, not one measured on largemouth. A bass in 65-degree water and one in 45-degree water are running at very different speeds on the same day.
The major and minor periods in our piece on solunar activity phases don't stop in November. A cold bass just doesn't need much from them, so even a good window can feel quiet.
Up North, the lake goes quiet from the top down
What 40-degree water does to a bass
The Great Lakes Fishery Commission's temperature data puts the point where largemouth stop growing at about 50°F. Below that, a meal takes a long time to digest and they won't chase anything that looks like hard work.
Why deep, and why bunched up? Water is heaviest at about 39°F, so as a northern lake heads toward ice, the deep basin becomes the steadiest water in the lake, out of reach of cold fronts and wind. Under the ice, the deepest water is actually the warmest. A 2008 study that tracked largemouth through a winter in an Ontario lake found them in the deepest water, barely moving. Their perch, shiners and ciscoes gather on a few spots, so the bass stack up there, often 15 to 30-plus feet down on steep breaks and hard-bottom humps.
Two catches. Largemouth with green weeds nearby can sit shallower, around 8 to 15 feet. And in fertile lakes the deepest hole can run low on oxygen under ice. Tracked bass avoided water under about 2 mg/L. We get into specific structure in our winter bass guide.
How to fish it up North
Start with your electronics. In cold water an empty spot stays empty. A drop shot is hard to beat: a 3- or 4-inch minnow or finesse worm, a 12- to 18-inch tag, 6-pound fluorocarbon. Shake the slack line, not the bait, and leave it still longer than feels right. A half-ounce blade bait fished straight down is the other one we lean on. Lift it a foot or so, let it fall back on a semi-tight line, and expect most bites on the fall. Whatever you throw, slow down. Then slow down more.
Down South, the shad pull everything shallow
Why the 60s are the sweet spot
Across a lot of the South, the water is still in the 60s in mid-November, often the mid-60s, and some Texas reservoirs run warmer. That's well above the 50-degree line, so those bass still have most of their summer energy.
Threadfin shad don't handle cold. In a 1963 lab study for the Southeastern Association of Fish and Wildlife Agencies, threadfin kept at 59°F died quickly once the water hit 41°F, which is a big reason they're mostly a Southern baitfish. In fall, big schools move into creek arms and up onto flats. Biologists still argue about why, but you've probably seen it.
This is where the "feeding up" line goes wrong again. Southern bass aren't hungrier than they were in July. Their food has piled into shallow water that's still warm enough to chase it in, and that's what people are seeing when they talk about a fall frenzy.
How to fish it down South
Cover water. A half-ounce lipless crankbait in a shad color, burned across flats and ripped out of any grass it hangs on, finds fish fast. After that, a spinnerbait or squarebill on wind-blown wood and rock in the back of a creek.
Fish busting on top are usually small. The bigger ones hang underneath, so run a swimbait under the school. No shad in fifteen minutes? Move. This time of year, finding the bait is finding the fish.
Late fall isn't spring in reverse
48 degrees in March and 48 degrees in November aren't the same thing. In March the water's warming and the spawn is pulling bass toward the bank. In November they're headed the other way. We cover the spring side in reading the pre-spawn transition. Fish November like it's March and you'll be casting to water the fish left weeks ago.
Stop fishing the calendar
November is really two seasons, sometimes on the same reservoir. What decides your day is the water temperature, which arms are clear, and where the wind is pushing bait.
That's what we built Bassfinity Pro for. It's $39.99 a year, about $3.33 a month, which is less than the cost of a single premium hardbait to unlock the whole lake before you launch. The Intelligence Map shows water clarity, streamflow and hot zones. SpotLens shows community spots, and the ones with five or more ratings from real catches get marked Verified. TackleLens recommends gear for the temperature, clarity and light you're actually fishing.
For comparison, the best-known premium fishing app lists its annual plan at $79.99 on the US App Store. That's twice what we charge.
Every number here is an average, so bring a thermometer and trust your own lake over us. For the whole fall picture, read Fall Bass: Turnover and the Bait Migration.
Tight lines.
