San Pablo Bay (California) — a spot well known among anglers. About 263.4 km² in area. Close by — Vallejo, Richmond and San Rafael. A coastal water: the bite here is modelled for the sea, not for a river or a lake. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

Catches

Recorded 2 catches here. Most commonly caught: Striped bass. Peak season: February.

    Hourly activity

    Bite activity:highmediumlow

    The bite is strong — fish are active. Weather is steady, with no sharp swings — fish behave predictably.

    Peak bite hours

    Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).

    Tactics

    Look for structure — reefs, flats, channel edges; work them slowly near the bottom.

    Lures

    The water's turning murky — go with bright, noisy lures: trolling spoon or spinner.

    Gear

    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.

    Summary

    Worth going — it's a productive day.

    How this forecast is calculated

    Why this forecast

    The computed water temperature is around 78 °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.

    The day: daylight hours and when Coho salmon feeds0:0012:0024:00

    Pressure is dropping 0.06 inHg 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.

    Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.

    Solunar feeding periods

    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.
