Ripple River (Manitoba) — a spot well known among anglers. About 35 km long. The town of York Landing is nearby. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Wednesday, September 2
The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably.
Best time — 06:00–08:00 (dawn bite) and 20:00–22:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
In clear water, natural colors work best: spoon or large fly.
Pack transitional-season clothing — mornings and evenings are chilly.
Worth going — it's a productive day.
The computed water temperature is around 13 °C — warmer than the 1–10 °C comfort range for Arctic char: in the heat it drops deeper and feeds less often.
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 rising 4 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 peak season for Arctic char here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +15°
The day is 5 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.
