Thesiger Bay (Northwest Territories) — one of the area's fishing spots. About 2221.9 km² in area. Salt water, not fresh — so this page carries its own marine bite forecast. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
The shoreline is moderately indented: bays and points alternate with even stretches.
The wind builds its wave along the north-west — south-east axis — 140 km of open water; along north-east — south-west there is only 27 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.
Northwest Territories: the months when each species peaks and when it goes quiet. The current month is outlined.

Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Thesiger Bay — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 09:00–11:00 and 18:00–19:00.
The computed water temperature is around 5 °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 rising 29 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.
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
Open-Meteo Marine model, grid cell 2.2 km from the waterbody. Values are daily means.
Showers · feels like -6°
The day is 10 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldquiet, Kp 3.7
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.
