Black crappie

3/10 · Weak

Hourly activity

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

The bite is weak — fish are sluggish. A thunderstorm is possible: activity rises before the front and drops after.

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

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

Gear

Pack transitional-season clothing — mornings and evenings are chilly. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

Summary

A slow day — go only if you really feel like it.

How this forecast is calculated

Why this forecast

The computed water temperature is around 53 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.

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 0.27 inHg 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.
