Recorded 4 catches of Grayling in South Yorkshire. Most active — September–November. A day-by-day bite calendar for Grayling.
Thursday, September 3
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued.
Best time — 11:00–16:00 (daytime activity).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: fly or small spinner.
No special gear needed — seasonal clothing will do. Rain is expected — don't forget a rain jacket or a waterproof shell.
Worth going — it's a productive day.
The computed water temperature is around 17 °C — inside the 6–18 °C comfort range for Grayling, so baseline activity is high.
Grayling 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.
September is peak season for Grayling here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +18°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
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.
