    6/10 · Fair

    Hourly activity

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

    The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably.

    Peak bite hours

    Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

    Tactics

    Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.

    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. Rain is expected — don't forget a rain jacket or a waterproof shell.

    Summary

    An average day — best chances during peak windows.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 68 °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 flat: it moves no more than 0.03 inHg over the day, so the weather isn't shifting today's bite.

    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.
