What is a bite calendar?
Sea

Hourly activity

0:006:0012:0018:0023:00
Bite activity:highmediumlow

The bite is weak — fish are sluggish. Pressure is dropping — this usually boosts the bite.

Peak bite hours

Best time — 06:00–07:00 (dawn bite) and 20:00–21:00 (dusk bite).

Tactics

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

Lures

The water's turning murky — go with bright, noisy lures: pirk or lugworm bottom rig.

Gear

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

Summary

A slow day — go only if you really feel like it.

Why this forecast

The computed water temperature is around 13 °C — warmer than the 4–12 °C comfort range for Atlantic cod: in the heat it drops deeper and feeds less often.

Pressure is flat: it moves no more than 1 hPa over the day, so the weather isn't shifting today's bite.

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.
