Gerrans Bay (British Columbia) — a popular fishing spot. About 83 ha in area. This is a sea water — its bite forecast is a marine one, computed apart from rivers and lakes. 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. The islands add structure: drop-offs around their perimeter and channels between them and the bank. Larger than 19 of the 20 waters nearby.
The longest fetch is 2 km along the north-east — south-west axis: wind along it builds a wave on the open water and pushes silt and food towards the lee bank.

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.
Gerrans Bay — Tuesday, October 20
The bite is strong — fish are active. Pressure is rising — activity tends to be more subdued. Peak 08:00–10:00 and 18:00–20:00.
The computed water temperature is around 3 °C — colder than the 6–17 °C comfort range for Brown trout: the fish conserves energy and takes more cautiously.
Brown trout works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is flat: it moves no more than 1 hPa over the day, so the weather isn't shifting today's bite.
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 Brown trout here.

Clear · feels like -1°
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 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.
