South Bay (Ontario) — a spot well known among anglers. About 11 km² in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. Larger than 4 of the 6 waters nearby.
The wind builds its wave along the north-east — south-west axis — 7 km of open water; along west — east there is only 4 km. 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. The water's cold — fish it more delicately and slowly.
South Bay — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued. Peak 08:00–09:00 and 18:00–20:00.
The computed water temperature is around 8 °C — inside the 4–14 °C comfort range for Atlantic salmon, so baseline activity is high.
Atlantic salmon works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is rising 1 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.
October is an active season for Atlantic salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Open-Meteo Marine model, grid cell 15.4 km from the waterbody. Values are daily means.
Drizzle · feels like +7°
The day is 3 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA forecast. 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.
