The bite is moderate — fish feed in short bursts. A thunderstorm is possible: activity rises before the front and drops after.
Best time — 06:00–08:00 (dawn bite) and 20:00–21:00 (dusk bite).
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
The water's turning murky — go with bright, noisy lures: small jig or minnow bait.
No special gear needed — seasonal clothing will do. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.
An average day — best chances during peak windows.
The computed water temperature is around 67 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.
Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is flat: it moves no more than 0.00 inHg over the day, so the weather isn't shifting today's bite.
One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.
September is an active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +75°
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.
