Grafham Water — Tuesday, November 3
The bite is weak — fish are sluggish. Weather is steady, with no sharp swings — fish behave predictably. Peak 07:00–08:00 and 16:00–17:00.
The computed water temperature is around 11 °C — inside the 6–16 °C comfort range for Rainbow trout, so baseline activity is high.
Rainbow 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 2 hPa over the day — fish are usually more active ahead of a weather change.
November is a slow season for Rainbow trout: 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 +8°
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 fieldquiet, Kp 2
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.
