Boy Lake (Montana) — a popular fishing spot. About 5 ha in area. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.
Cloudy: 37–64 °F
Saturday, September 5
The bite is moderate — fish feed in short bursts. A thunderstorm is possible: activity rises before the front and drops after.
Best time — 07:00–08:00 (dawn bite) and 20:00–22:00 (dusk bite).
Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.
The water's turning murky — go with bright, noisy lures: small jig or minnow bait.
Bring a warm jacket — it's noticeably colder on the water than on shore. A thunderstorm is possible — bring a rain jacket, and pack up at the first rumble of thunder.
An average day — best chances during peak windows.
The computed water temperature is around 49 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.
Black crappie works the twilight: the peaks are pinned to sunrise and sunset — their times are in the sun-and-moon card above.
Pressure is rising 0.03 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.
September is an average month for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Clear · feels like +39°
The day is 3 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.
