Bay Saint Croix River Estuary (Maine) — a spot well known among anglers. About 30.6 km² in area. The town of Calais is nearby. 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 shoreline is heavily indented — bays, points and spits. Look for pike at the mouths of the bays and on the drop-offs behind the points. The largest water around: all 18 neighbours are smaller.
The wind builds its wave along the north-west — south-east axis — 13 mi of open water; along north-east — south-west there is only 5 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.

|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Striped bass | slow | slow | fair | active | peak | peak | active | active | active | peak | active | fair |

Look for structure — reefs, flats, channel edges; work them slowly near the bottom.
Saint Croix River Estuary — Tuesday, October 20
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued. Peak 07:00–09:00 and 17:00–19:00.
The computed water temperature is around 48 °F — inside the 39–57 °F comfort range for Atlantic salmon, so baseline activity is high.
Atlantic 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 0.18 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 Atlantic salmon here.

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.
