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 — 00:00–05:00 (nighttime activity).

Tactics

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.

Lures

In clear water, natural colors work best: soft-plastic jig or live bait.

Gear

It's a hot day — a hat, sunglasses, and plenty of water are a must.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 85 °F — warmer than the 61–79 °F comfort range for Black drum: in the heat it drops deeper and feeds less often.

Black drum feeds at night: the peak falls in the dark hours, between sunset and sunrise.

The day: daylight hours and when Black drum feeds0:0012:0024:00

Pressure is dropping 0.03 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.

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.
