    The day is 3 min shorter than yesterday.

    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.

    Recommendations

    Tactics

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

    Lures

    Today's bait — worm or tiny jig. In cold or murky water, add scent to your chum.

    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.
