Bay Loch Hourn (Highland) — a spot well known among anglers. About 2.8 km² in area. 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.
Drizzle: 9–12 °C
Saturday, September 5
The bite is weak — fish are sluggish. A thunderstorm is possible: activity rises before the front and drops after.
Best time — 07:00–08:00 (dawn bite) and 20:00–21:00 (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.
Pack transitional-season clothing — mornings and evenings are chilly. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.
A slow day — go only if you really feel like it.
The computed water temperature is around 12 °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 rising 14 hPa over the day — the bite usually settles down after a rise.
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 a slow season for Atlantic cod: the best months fall at another time of year.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +7°
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.
