Bleak

4/10 · Weak

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 — 11:00–16:00 (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 16 °C — inside the 14–26 °C comfort range for Bleak, so baseline activity is high.

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 9 hPa over the day — fish are usually more active ahead of a weather change.

Pressure through the day, 9 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.

September is a slow season for Bleak: the best months fall at another time of year.
