What is a bite calendar?

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 — 11:00–14:00 and 15:00–16:00 (daytime activity).

Tactics

Pick a stretch of steady current, chum one spot and fish it — don't move around without reason.

Lures

Today's bait — worm or bread crust. In cold or murky water, add scent to your chum.

Gear

No special gear needed — seasonal clothing will do. 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.

Why this forecast

The computed water temperature is around 14 °C — colder than the 16–28 °C comfort range for Rudd: the fish conserves energy and takes more cautiously.

Solunar feeding periods

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.
