Flathead catfish lives in South Dakota. Today's bite forecast, a day-by-day and hour-by-hour activity calendar, best time and baits.
Saturday, September 5
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.
Best time — 00:00–05:00 and 23:00–23:00 (nighttime activity).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: live-bait bottom rig or large bottom bait.
It's a hot day — a hat, sunglasses, and plenty of water are a must. Rain is expected — don't forget a rain jacket or a waterproof shell.
An average day — best chances during peak windows.
The computed water temperature is around 74 °F — inside the 70–86 °F comfort range for Flathead catfish, so baseline activity is high.
Flathead catfish feeds at night: the peak falls in the dark hours, between sunset and sunrise.
Pressure is rising 0.06 inHg over the day — the bite usually settles down after a rise.
September is an average month for Flathead catfish here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +82°
The day is 3 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
The windows are set by the moon's transit and rise, and the forecast above already accounts for them: within these hours the bite score sits higher than across the rest of the day, while the day's overall level still comes from the catch-calibrated model.
