Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Manitoba — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued. Peak 00:00–04:00 and 23:00–23:00.
The computed water temperature is around 6 °C — inside the -1–8 °C comfort range for Shorthorn sculpin, so baseline activity is high.
Shorthorn sculpin feeds at night: the peak falls in the dark hours, between sunset and sunrise.
Pressure is flat: it moves no more than 0 hPa over the day, so the weather isn't shifting today's bite.
October is an active season for Shorthorn sculpin here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +1°
The day is 5 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 forecast. 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.
