Saginaw Bay (Michigan) — a spot well known among anglers. About 2876.8 km² in area. A coastal water: the bite here is modelled for the sea, not for a river or a lake. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Recorded 32 catches here. Most commonly caught: Walleye, Yellow perch, Lake trout. Peak season: January–September.
Cloudy: 59–79 °F
Thursday, September 3
The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably.
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.
In clear water, natural colors work best: trolling spoon or spinner.
It's a hot day — a hat, sunglasses, and plenty of water are a must.
Worth going — it's a productive day.
The computed water temperature is around 67 °F — warmer than the 43–59 °F comfort range for Coho salmon: in the heat it drops deeper and feeds less often.
Coho 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 0.06 inHg 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 peak season for Coho salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Open-Meteo Marine model, grid cell 1.2 mi from the waterbody. Values are daily means.
Cloudy · feels like +75°
The day is 3 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.

This is a summary of anglers' reports, not a proven cause of the bite: conditions lining up does not mean they drove it.
