Bay Gluss Voe (Shetland) — one of the area's fishing spots. About 1.2 km² in area. Salt water, not fresh — so this page carries its own marine bite forecast. This page shows an hourly bite forecast for today and the week ahead; the algorithm factors in the weather, atmospheric pressure, and the moon phase.
Other nearby waters
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. Larger than 18 of the 20 waters nearby.
The wind builds its wave along the north-east — south-west axis — 2 mi of open water; along north-west — south-east there is only 1 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. The water's cold — fish it more delicately and slowly.
Gluss Voe — Wednesday, October 21
The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite. Peak 08:00–10:00 and 17:00–19:00.
The computed water temperature is around 9 °C — inside the 4–12 °C comfort range for Atlantic cod, so baseline activity is high.
Atlantic cod works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is dropping 15 hPa 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 Atlantic cod here.

Open-Meteo Marine model, grid cell 2.3 mi from the waterbody. Values are daily means.
Drizzle · feels like +4°
The day is 5 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldunsettled, Kp 4
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.
