Penobscot River (Maine) — a popular fishing spot. About 100 km long. The town of Bangor is nearby. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Cloudy: 52–68 °F
Recorded 2 catches here. Most commonly caught: Largemouth bass, Smallmouth bass. Peak season: July–August.
Wednesday, September 2
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued.
Best time — 05:00–07:00 (dawn bite) and 19:00–21:00 (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.
Worth going — it's a productive day.
The computed water temperature is around 64 °F — warmer than the 39–57 °F 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 dropping 0.06 inHg 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.
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 +65°
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.
