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.
Recorded 1 catch here. Most commonly caught: Grayling. Peak season: June.
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.
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Cardigan Bay — Friday, September 18
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 06:00–08:00 and 19:00–21:00.
The computed water temperature is around 15 °C — warmer than the 4–12 °C comfort range for Atlantic cod: in the heat it drops deeper and feeds less often.
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 flat: it moves no more than 1 hPa over the day, so the weather isn't shifting today's bite.
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.
September is an active season for Atlantic cod here.

Cloudy · feels like +13°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
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.
