    3/10 · Weak

    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 — 12:00–17:00 (daytime activity).

    Tactics

    Chum one spot near a drop-off and wait for fish to arrive — don't chase them.

    Lures

    Today's bait — maggot or small hook with dough bait. In cold or murky water, add scent to your chum.

    Gear

    No special gear needed — seasonal clothing will do. Rain is expected — don't forget a rain jacket or a waterproof shell.

    Summary

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

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 15 °C — inside the 14–26 °C comfort range for Bleak, so baseline activity is high.

    Bleak feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.

    The day: daylight hours and when Bleak feeds0:0012:0024:00

    Pressure is rising 10 hPa over the day — the bite usually settles down after a rise.

    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.

    September is a slow season for Bleak: the best months fall at another time of year.

    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.
