    What is a bite calendar?

    Hourly activity

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

    The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.

    Peak bite hours

    Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

    Tactics

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

    Lures

    In clear water, natural colors work best: trout paste or trout spoon.

    Gear

    No special gear needed — seasonal clothing will do.

    Summary

    An average day — best chances during peak windows.

    Why this forecast

    The computed water temperature is around 18 °C — warmer than the 6–16 °C comfort range for Rainbow trout: in the heat it drops deeper and feeds less often.

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

    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.
