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 rising — activity tends to be more subdued.

Peak bite hours

Best time — 07:00–08:00 (dawn bite) and 20:00–21:00 (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

Pack transitional-season clothing — mornings and evenings are chilly.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 17 °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 2 hPa over the day — the bite usually settles down after a rise.

Pressure through the day, 2 hPa 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.
