Lake Doire Lochan (Argyll and Bute) — a popular fishing spot. About 2 ha in area. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Argyll and Bute: the months when each species peaks and when it goes quiet. The current month is outlined.

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. Smaller than 8 of the 10 waters nearby.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.
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.
Doire Lochan — Wednesday, October 21
The bite is weak — fish are sluggish. Pressure is dropping — this usually boosts the bite. Peak 12:00–15:00.
The computed water temperature is around 11 °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 rising 4 hPa over the day — the bite usually settles down after a rise.
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
Cloudy · feels like +6°
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.
