    What is a bite calendar?

    Hourly activity

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

    The bite is weak — fish are sluggish. Pressure is dropping — this usually boosts the bite.

    Peak bite hours

    Best time — 06:00–08:00 (dawn bite) and 20:00–22:00 (dusk bite).

    Tactics

    Pick a stretch of steady current, chum one spot and fish it — don't move around without reason.

    Lures

    Today's bait — tiny jig with shrimp or sabiki rig.

    Gear

    No special gear needed — seasonal clothing will do.

    Summary

    A slow day — go only if you really feel like it.

    Why this forecast

    The computed water temperature is around 17 °C — warmer than the 0–8 °C comfort range for Rainbow smelt: 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.
