Tuesday, November 3
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Afon Trystion — Tuesday, November 3
The bite is weak — fish are sluggish. Pressure is rising — activity tends to be more subdued. Peak 07:00–09:00 and 16:00–18:00.
The computed water temperature is around 9 °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 dropping 4 hPa over the day — fish are usually more active ahead of a weather change.
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.
November is a slow season for Atlantic salmon: 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 +6°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldquiet, Kp 2
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
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.

The course runs nearly straight: there are few bend pools, and the structure to look for is riffles and scour holes. Shorter than 13 of the 15 rivers nearby.
