Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Alberta — Tuesday, October 20
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued. Peak 11:00–17:00.
The computed water temperature is around 3 °C — colder than the 6–18 °C comfort range for Grayling: the fish conserves energy and takes more cautiously.
Going by this year's frosts the ice hasn't formed yet: the season says it should have, but it hasn't been cold enough. This is an estimate from the weather across the whole region, not a measurement on your water.
Grayling feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is rising 4 hPa over the day — the bite usually settles down after a rise.
October is an active season for Grayling here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like -4°
The day is 4 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.
