River Tavy (Devon) — one of the area's fishing spots. About 42 km long. Flows into River Tamar. The town of Plymouth is nearby. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Recorded 2 catches here. Most commonly caught: Brown trout. Peak season: August–September.
Cloudy: 12–17 °C
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 19:00–21:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: salmon spoon or salmon fly.
Pack transitional-season clothing — mornings and evenings are chilly. Rain is expected — don't forget a rain jacket or a waterproof shell.
An average day — best chances during peak windows.
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 rising 3 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
Drizzle · feels like +7°
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.
