Reservoir Lake Joyce (Virginia) — a spot well known among anglers. About 29 ha in area. Nearby towns: Virginia Beach, Norfolk and Portsmouth. 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.
Partly cloudy: 63–93 °F
The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.
Best time — 07:00–08:00 (dawn bite) and 19:00–21:00 (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.
It's a hot day — a hat, sunglasses, and plenty of water are a must. Rain is expected — don't forget a rain jacket or a waterproof shell.
An average day — best chances during peak windows.
The computed water temperature is around 68 °F — inside the 57–75 °F comfort range for Black crappie, so baseline activity is high.
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 0.12 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 active season for Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +76°
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.
