Wednesday, September 2
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite.
Best time — 06:00–08:00 (dawn bite) and 20:00–22:00 (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.
No special gear needed — seasonal clothing will do.
An average day — best chances during peak windows.
The computed water temperature is around 17 °C — warmer than the 4–14 °C comfort range for Atlantic salmon: in the heat it drops deeper and feeds less often.
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 2 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 +20°
The day is 3 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.
What are solunar periods?Recorded 16 catches here. Most commonly caught: Bluegill, Channel catfish, Smallmouth bass. Peak season: June–August.
