    6/10 · Fair

    Hourly activity

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

    The bite is moderate — fish feed in short bursts. A thunderstorm is possible: activity rises before the front and drops after.

    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

    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.

    Summary

    An average day — best chances during peak windows.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 74 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.

    Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.

    The day: daylight hours and when Black crappie feeds0:0012:0024:00

    Pressure is dropping 0.09 inHg over the day — fish are usually more active ahead of a weather change.

    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.

    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.
