Sea Strait of Juan de Fuca (Washington) — a spot well known among anglers. About 4000.3 km² in area. 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.
Other nearby waters
The shoreline is moderately indented: bays and points alternate with even stretches. There are many islands: the water is broken up by drop-offs and the channels between them.
The wind builds its wave along the west — east axis — 97 mi of open water; along north — south there is only 37 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.
Washington: the months when each species peaks and when it goes quiet. The current month is outlined.

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Strait of Juan de Fuca — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably. Peak 07:00–09:00 and 18:00–19:00.
The computed water temperature is around 57 °F — inside the 43–59 °F comfort range for Coho salmon, so baseline activity is high.
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 0.06 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.
October is an active season for Coho salmon here.

Cloudy · feels like +59°
The day is 3 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.
