    Arctic char

    10/10 · Good

    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 — 05:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

    Tactics

    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.

    Lures

    In clear water, natural colors work best: 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.

    Summary

    Worth going — it's a productive day.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 9 °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 5 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.
