Grand River (Prince Edward Island) — one of the area's fishing spots. About 8 km long. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.
The course runs nearly straight: there are few bend pools, and the structure to look for is riffles and scour holes.

Wednesday, October 21
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
Grand River — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably. Peak 07:00–09:00 and 18:00–20:00.
The computed water temperature is around 10 °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 dropping 3 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.
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
Partly cloudy · feels like +5°
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 fieldunsettled, Kp 4
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.
