Bay Gem Cove (Alaska) — a popular fishing spot. About 25 ha in area. The town of Ketchikan is nearby. This is a sea water — its bite forecast is a marine one, computed apart from rivers and lakes. A smart bite calendar — moon phase, atmospheric pressure, and weather combined into an hourly fish-activity forecast for the coming days.

The shoreline is moderately indented: bays and points alternate with even stretches. Smaller than 8 of the 11 waters nearby.
The water is sheltered: there is almost no fetch, so wind stirs it up very little.

Green check: this species was recorded here by GBIF. Species without a check may still occur in the waterbody.
Look for structure — reefs, flats, channel edges; work them slowly near the bottom. The water's cold — fish it more delicately and slowly.
Gem Cove — Tuesday, October 20
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 09:00–11:00 and 19:00–21:00.
The computed water temperature is around 38 °F — colder than the 43–59 °F comfort range for Coho salmon: the fish conserves energy and takes more cautiously.
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 0.41 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 peak season for Coho salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Open-Meteo Marine model, grid cell 5.5 mi from the waterbody. Values are daily means.
Snow · feels like +23°
The day is 4 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.
