8 verified Chinook salmon catches are linked to San Francisco Bay. The forecast below uses this waterbody and current weather data.
Hourly activity and a seven-day calendar for Chinook salmon.
Monday, September 7
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 19:00–20:00 (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 trolling plug.
It's a hot day — a hat, sunglasses, and plenty of water are a must.
An average day — best chances during peak windows.
The computed water temperature is around 79 °F — warmer than the 43–59 °F comfort range for Chinook salmon: in the heat it drops deeper and feeds less often.
Chinook 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 0.03 inHg over the day — the bite usually settles down after a rise.
September is an average month for Chinook salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +83°
The day is 2 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.
What are solunar periods?Recorded 8 catches here. Most commonly caught: Chinook salmon. Peak season: July.
