    What is a bite calendar?

    Hourly activity

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

    The bite is strong — fish are active. A thunderstorm is possible: activity rises before the front and drops after.

    Peak bite hours

    Best time — 06:00–07:00 (dawn bite) and 20:00–21:00 (dusk bite).

    Tactics

    Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.

    Lures

    The water's turning murky — go with bright, noisy lures: spinner or small crankbait.

    Gear

    No special gear needed — seasonal clothing will do. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

    Summary

    Worth going — it's a productive day.

    Why this forecast

    The computed water temperature is around 14 °C — inside the 6–17 °C comfort range for Brown trout, so baseline activity is high.

    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.
