Bay West Arm (British Columbia) — a spot well known among anglers. About 34.3 km² in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. 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.

Catches

Recorded 6 catches here. Most commonly caught: Sockeye salmon, Yellow perch. Peak season: July–October.

    Hourly activity

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

    The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.

    Peak bite hours

    Best time — 06:00–09:00 (dawn bite) and 20:00–22:00 (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: spinner or small crankbait. 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 6–17 °C comfort range for Brown trout, so baseline activity is high.

    Brown trout 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 Brown trout feeds0:0012:0024:00

    Pressure is rising 6 hPa over the day — the bite usually settles down after a rise.

    Pressure through the day, 6 hPa change
    00:00 · 100623:00 · 1011 hPa

    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 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.
