    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

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

    Lures

    The water's turning murky — go with bright, noisy lures: small jig or minnow bait.

    Gear

    It's a hot day — a hat, sunglasses, and plenty of water are a must. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.
