Sea Le Petit Passage (Quebec) — a spot well known among anglers. About 96 ha in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. The islands add structure: drop-offs around their perimeter and channels between them and the bank. Larger than 13 of the 20 waters nearby.
The longest fetch is 2 km along the north-east — south-west axis: wind along it builds a wave on the open water and pushes silt and food towards the lee bank.

Wednesday, October 21
Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Le Petit Passage — Wednesday, October 21
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 08:00–09:00 and 17:00–19:00.
The computed water temperature is around 4 °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 3 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.

Cloudy · feels like -2°
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 fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA forecast. 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.
