Langton Bay (Northwest Territories) — a spot well known among anglers. About 194.9 km² in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.

    9/10 · Good

    Hourly activity

    0:006:0012:0018:0023:00
    Bite activity:highmediumlow

    The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued.

    Peak bite hours

    Best time — 07:00–09:00 (dawn bite) and 21:00–23:00 (dusk bite).

    Tactics

    Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.

    Lures

    The water's turning murky — go with bright, noisy lures: spoon or large fly. The water's cold — work the lure slower than usual.

    Gear

    Bring a warm jacket — it's noticeably colder on the water than on shore. Rain is expected — don't forget a rain jacket or a waterproof shell.

    Summary

    Worth going — it's a productive day.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 7 °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.

    The day: daylight hours and when Arctic char feeds0:0012:0024:00

    Pressure is dropping 8 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.

    The day is 9 min shorter than yesterday.

    Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.

    Major periodsMinor periods

    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.
