Sea

Hourly activity

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

The bite is moderate — fish feed in short bursts. A thunderstorm is possible: activity rises before the front and drops after.

Peak bite hours

Best time — 07:00–08:00 (dawn bite) and 20:00–22:00 (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. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.

Summary

An average day — best chances during peak windows.

Why this forecast

The computed water temperature is around 14 °C — warmer than the 4–12 °C comfort range for Atlantic cod: in the heat it drops deeper and feeds less often.

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.
