Jackfish Lake (Manitoba) — one of the area's fishing spots. About 69 ha in area. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. Larger than 10 of the 14 waters nearby.
The wind builds its wave along the north-west — south-east axis — 2 km of open water; along west — east there is only 0.8 km. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots. The water's cold — fish it more delicately and slowly.
Jackfish Lake — Tuesday, October 20
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued. Peak 08:00–10:00 and 18:00–20:00.
The computed water temperature is around 6 °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 2 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.
October is an active season for Arctic char here.
These are the same values the bite curve above was computed from. How the forecast works
Drizzle · feels like 0°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldunsettled, Kp 4
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the bite.
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.
