Indiana — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 11:00–17:00.
The computed water temperature is around 61 °F — inside the 54–72 °F comfort range for Yellow perch, so baseline activity is high.
Yellow perch feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is dropping 0.03 inHg over the day — fish are usually more active ahead of a weather change.
October is an active season for Yellow perch here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +61°
The day is 2 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
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.
