Recorded 1 catch of Flounder in Cumbria. Most active — August. A day-by-day bite calendar for Flounder.
Friday, September 4
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite.
Best time — 00:00–04:00 and 22:00–23:00 (nighttime activity).
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
The water's turning murky — go with bright, noisy lures: soft-plastic jig or live bait.
Pack transitional-season clothing — mornings and evenings are chilly. Rain is expected — don't forget a rain jacket or a waterproof shell.
An average day — best chances during peak windows.
The computed water temperature is around 13 °C — inside the 12–24 °C comfort range for Flounder, so baseline activity is high.
Flounder feeds at night: the peak falls in the dark hours, between sunset and sunrise.
Pressure is rising 5 hPa over the day — the bite usually settles down after a rise.
September is peak season for Flounder here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +9°
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.
