Hourly activity

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. Winds will be strong — wind protection helps, and be careful if you're in a boat.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 70 °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.
