Cardigan Bay (Ceredigion) — a spot well known among anglers. About 3780.3 km² in area. Close by — Aberystwyth and Cardigan. A coastal water: the bite here is modelled for the sea, not for a river or a lake. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
Nearest towns and cities
The basin is close to regular: the bank runs smooth and natural cover is scarce, so fish hold to the few anomalies — inflows, drop-offs and weed edges.
The wind builds its wave along the north-east — south-west axis — 70 mi of open water; along north-west — south-east there is only 39 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.

Tuesday, November 3
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Cardigan Bay — Tuesday, November 3
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued. Peak 07:00–09:00 and 17:00–18:00.
The computed water temperature is around 10 °C — inside the 4–12 °C comfort range for Atlantic cod, so baseline activity is high.
Atlantic cod works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 5 hPa over the day — fish are usually more active ahead of a weather 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.
November is peak season for Atlantic cod here.

Clear · feels like +7°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldquiet, Kp 2
Kp index — NOAA data. Not part of the bite score: catches show no link between geomagnetic storms and the 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.
