    Black crappie

    4/10 · Weak

    Hourly activity

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

    The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite.

    Peak bite hours

    Best time — 06:00–08:00 (dawn bite) and 20:00–22:00 (dusk bite).

    Tactics

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

    Lures

    In clear water, natural colors work best: small jig or minnow bait.

    Gear

    No special gear needed — seasonal clothing will do.

    Summary

    An average day — best chances during peak windows.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 16 °C — inside the 14–24 °C 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 rising 4 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.

    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.
