Bay Ayala Cove (California) — a spot well known among anglers. About 8 ha in area. Close by — San Francisco, Richmond and Berkeley. 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.

The basin is close to regular: the bank runs smooth and natural cover is scarce, so fish hold to the few anomalies — inflows, drop-offs and weed edges. Smaller than 12 of the 16 waters nearby.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.
California: the months when each species peaks and when it goes quiet. The current month is outlined.

Ayala Cove — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 06:00–08:00 and 18:00–19:00.
The computed water temperature is around 68 °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 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.
October is an average month 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.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
Kp index — NOAA data. 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.
