Recorded 5 catches of Flathead catfish in Arizona. Most active — September–November. A day-by-day bite calendar for Flathead catfish.
Friday, September 4
The bite is weak — fish are sluggish. Weather is steady, with no sharp swings — fish behave predictably.
Best time — 00:00–04:00 and 22:00–23:00 (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. Winds will be strong — wind protection helps, and be careful if you're in a boat.
A slow day — go only if you really feel like it.
The computed water temperature is around 91 °F — warmer than the 70–86 °F comfort range for Flathead catfish: in the heat it drops deeper and feeds less often.
Flathead catfish feeds at night: the peak falls in the dark hours, between sunset and sunrise.
Pressure is rising 0.09 inHg over the day — the bite usually settles down after a rise.
September is a slow season for Flathead catfish: the best months fall at another time of year.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +94°
The day is 2 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.
