Chum one spot near a drop-off and wait for fish to arrive — don't chase them.
Derrybrick Lough — Wednesday, October 21
The bite is weak — fish are sluggish. A thunderstorm is possible: activity rises before the front and drops after. Peak 11:00–15:00.
The computed water temperature is around 10 °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 7 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 +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 fieldunsettled, Kp 4
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.

Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. The islands add structure: drop-offs around their perimeter and channels between them and the bank. Larger than 17 of the 20 waters nearby.
The wind builds its wave along the north — south axis — 1 mi of open water; along north-east — south-west 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.
