Recorded 15 catches of Smallmouth bass in Colorado. Most active — April–August. A day-by-day bite calendar for Smallmouth bass.
Wednesday, September 2
The bite is moderate — fish feed in short bursts. Weather is steady, with no sharp swings — fish behave predictably.
Best time — 06:00–08:00 (dawn bite) and 19:00–21:00 (dusk bite).
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
The water's turning murky — go with bright, noisy lures: jig with grub or crankbait.
It's a hot day — a hat, sunglasses, and plenty of water are a must. Winds will be strong — wind protection helps, and be careful if you're in a boat.
An average day — best chances during peak windows.
The computed water temperature is around 70 °F — inside the 59–75 °F comfort range for Smallmouth bass, so baseline activity is high.
Smallmouth bass works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.

These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +79°
The day is 2 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.
