Sea Carquinez Strait (California) — one of the area's fishing spots. About 26 km² in area. Close by — Vallejo, Concord and Richmond. Salt water, not fresh — so this page carries its own marine bite forecast. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Clear: 61–82 °F
Friday, September 4
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.
Best time — 06:00–07:00 (dawn bite) and 19:00–21:00 (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: trolling spoon or spinner.
It's a hot day — a hat, sunglasses, and plenty of water are a must. Winds will be strong — wind protection helps, and be careful if you're in a boat.
Worth going — it's a productive day.
The computed water temperature is around 77 °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 0.12 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.

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.
