Loch of Harray — Wednesday, October 21

The computed water temperature is around 11 °C — inside the 6–17 °C comfort range for Brown trout, so baseline activity is high.
Brown trout works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 8 hPa over the day — fish are usually more active ahead of a weather change.
October is an average month for Brown trout here.
These are the same values the bite curve above was computed from. How the forecast works
Drizzle · feels like +7°
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 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.
