Grayling lives in Cambridgeshire. Today's bite forecast, a day-by-day and hour-by-hour activity calendar, best time and baits.
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.
In clear water, natural colors work best: fly or small spinner.
No special gear needed — seasonal clothing will do.
Worth going — it's a productive day.
The computed water temperature is around 18 °C — warmer than the 6–18 °C comfort range for Grayling: in the heat it drops deeper and feeds less often.
Grayling feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is dropping 1 hPa over the day — fish are usually more active ahead of a weather change.
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 +20°
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.
