Recorded 64 catches of Chum salmon in British Columbia. Most active — September–November. A day-by-day bite calendar for Chum salmon.
Thursday, September 3
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite.
Best time — 06:00–09:00 (dawn bite) and 21:00–22:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses. The water's cold — fish it more delicately and slowly.
The water's turning murky — go with bright, noisy lures: bright fly or spinner. The water's cold — work the lure slower than usual.
Bring a warm jacket — it's noticeably colder on the water than on shore. Rain is expected — don't forget a rain jacket or a waterproof shell.
Worth going — it's a productive day.
The computed water temperature is around 7 °C — inside the 4–14 °C comfort range for Chum salmon, so baseline activity is high.
Chum 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 6 hPa over the day — the bite usually settles down after a rise.
September is peak season for Chum salmon here.
These are the same values the bite curve above was computed from. How the forecast works
Drizzle · feels like +2°
The day is 4 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
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.
