Bleak

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 — 12:00–17:00 (daytime activity).

Tactics

Chum one spot near a drop-off and wait for fish to arrive — don't chase them.

Lures

Today's bait — maggot or small hook with dough bait. In cold or murky water, add scent to your chum.

Gear

No special gear needed — seasonal clothing will do. Rain is expected — don't forget a rain jacket or a waterproof shell.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 14 °C — colder than the 14–26 °C comfort range for Bleak: the fish conserves energy and takes more cautiously.

Bleak feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.

The day: daylight hours and when Bleak feeds0:0012:0024:00

Pressure is dropping 5 hPa over the day — fish are usually more active ahead of a weather change.

Pressure through the day, 5 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.

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.
