Richardson Bay (California) — a spot well known among anglers. About 8.7 km² in area. Close by — San Rafael, San Francisco and Richmond. A coastal water: the bite here is modelled for the sea, not for a river or a lake. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.

The shoreline is moderately indented: bays and points alternate with even stretches. Larger than 15 of the 16 waters nearby.
The wind builds its wave along the north-west — south-east axis — 4 mi of open water; along north-east — south-west there is only 2 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.

Wednesday, October 21
Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Richardson Bay — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 06:00–08:00.
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 dropping 0.09 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 fieldquiet, Kp 3.7
Kp index — NOAA forecast. 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.
