Bay Loch Long (Argyll and Bute) — a popular fishing spot. About 32.7 km² in area. Close by — Helensburgh, Inveraray and Rothesay. This is a sea water — its bite forecast is a marine one, computed apart from rivers and lakes. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Cloudy: 14–16 °C
Sunday, September 6
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.
Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
The water's turning murky — go with bright, noisy lures: pirk or lugworm bottom rig.
No special gear needed — seasonal clothing will do. Rain is expected — don't forget a rain jacket or a waterproof shell.
An average day — best chances during peak windows.
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 dropping 10 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.
September is an active season for Atlantic cod here.
These are the same values the bite curve above was computed from. How the forecast works
Open-Meteo Marine model, grid cell 2.4 mi from the waterbody. Values are daily means.
Cloudy · feels like +15°
The day is 5 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.
