Best time — 06:00–08:00 (dawn bite) and 20:00–21:00 (dusk bite).
Pick a stretch of steady current, chum one spot and fish it — don't move around without reason.
Today's bait — tiny jig with shrimp or sabiki rig.
No special gear needed — seasonal clothing will do.
A slow day — go only if you really feel like it.
The computed water temperature is around 17 °C — warmer than the 0–8 °C comfort range for Rainbow smelt: in the heat it drops deeper and feeds less often.

Pressure is rising 4 hPa over the day — the bite usually settles down after a rise.
September is a slow season for Rainbow smelt: the best months fall at another time of year.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +19°
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.
