River Afon Twrch (Powys) — a popular fishing spot. About 17 km long. Flows into River Tawe. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Cloudy: 13–16 °C
Saturday, September 5
In the fish list, this icon marks species recorded here by GBIF. Unmarked species may still occur in the waterbody.
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.
Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
In clear water, natural colors work best: salmon spoon or salmon fly.
Pack transitional-season clothing — mornings and evenings are chilly.
An average day — best chances during peak windows.
The computed water temperature is around 14 °C — inside the 4–14 °C comfort range for Atlantic salmon, so baseline activity is high.
Atlantic salmon works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is rising 7 hPa over the day — the bite usually settles down after a rise.
One more input — the moon's feeding windows: within their hours the score sits higher than across the rest of the day. The window times are in the “Solunar feeding periods” card below.
September is an active season for Atlantic salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +13°
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.
