River Severn (Powys) — a spot well known among anglers. About 103 km long. Flows into Bristol Channel. Nearby towns: Newtown and Welshpool. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
The course meanders heavily: the current digs a pool on the outside of every bend and builds a bar on the inside. Those pools under the undercut bank are where pike typically sits. The longest river around: all 6 neighbours are shorter.
Partly cloudy: 12–18 °C
Recorded 2 catches here. Most commonly caught: Barbel, Grass carp. Peak season: September.

Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
River Severn — Friday, September 18
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 06:00–08:00 and 19:00–20:00.
The computed water temperature is around 13 °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 flat: it moves no more than 0 hPa over the day, so the weather isn't shifting today's bite.
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
Cloudy · feels like +10°
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.
