River Bras Saint-Nicolas (Quebec) — a spot well known among anglers. About 45 km long. Flows into Rivière du Sud, Rivière du Sud basin. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.
Best time — 05:00–08:00 (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 cold — fish it more delicately and slowly.
In clear water, natural colors work best: spoon or large fly. The water's cold — work the lure slower than usual.
Bring a warm jacket — it's noticeably colder on the water than on shore.
Worth going — it's a productive day.
The computed water temperature is around 9 °C — inside the 1–10 °C comfort range for Arctic char, so baseline activity is high.
Arctic char works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 5 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.
September is peak season for Arctic char here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +5°
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.
