Whitefish lives in Cardiff. Today's bite forecast, a day-by-day and hour-by-hour activity calendar, best time and baits.
Friday, September 4
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.
Best time — 07:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).
Pick a stretch of steady current, chum one spot and fish it — don't move around without reason.
Today's bait — jig fly with bloodworm or small fly. In cold or murky water, add scent to your chum.
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 — warmer than the 2–14 °C comfort range for Whitefish: in the heat it drops deeper and feeds less often.
Whitefish works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is rising 6 hPa over the day — the bite usually settles down after a rise.
September is peak season for Whitefish here.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +15°
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.
