What is a bite calendar?

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 — 06:00–08:00 (dawn bite) and 20:00–21:00 (dusk bite).

Tactics

Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.

Lures

The water's turning murky — go with bright, noisy lures: spinner or small crankbait.

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.

Why this forecast

The computed water temperature is around 15 °C — inside the 6–17 °C comfort range for Brown trout, so baseline activity is high.

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.
