Lower Glendevon Reservoir (Perth and Kinross) — a spot well known among anglers. About 40 ha in area. Close by — Auchterarder and Kinross. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Nearest towns and cities
The shoreline is heavily indented — bays, points and spits. Look for pike at the mouths of the bays and on the drop-offs behind the points. Larger than 8 of the 10 waters nearby.
The wind builds its wave along the west — east axis — 1 mi of open water; along north — south there is only 0.5 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.
Wednesday, October 21
Chum one spot near a drop-off and wait for fish to arrive — don't chase them. The water's cold — fish it more delicately and slowly.
Lower Glendevon Reservoir — Wednesday, October 21
The bite is weak — fish are sluggish. A thunderstorm is possible: activity rises before the front and drops after. Peak 11:00–16:00.
The computed water temperature is around 8 °C — colder than the 14–26 °C comfort range for Bleak: the fish conserves energy and takes more cautiously.
Bleak feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is flat: it moves no more than 1 hPa 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.
October is a slow season for Bleak: the best months fall at another time of year.
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.
