Guadalupe River (Texas) — a popular fishing spot. About 698 km long. Flows into San Antonio Bay. Close by — Victoria and New Braunfels. Here you'll find a bite prediction — when fish are active and which hours give the best chances, adjusted for weather and pressure.

The course meanders heavily: on the outside of every bend the current undercuts the bank and digs a pool, on the inside it builds a bar — that is the main structure the river has. The longest river around: all 6 neighbours are shorter.
Texas: the months when each species peaks and when it goes quiet. The current month is outlined. The bottom row counts the catches logged on this water in each month.

Green check: this species was recorded here by GBIF. Species without a check may still occur in the waterbody.
Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.
Guadalupe River — Tuesday, October 20
The bite is strong — fish are active. Pressure is dropping — this usually boosts the bite. Peak 08:00–09:00 and 19:00–21:00.
The computed water temperature is around 72 °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 flat: it moves no more than 0.03 inHg 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 Black crappie here.
These are the same values the bite curve above was computed from. How the forecast works
Partly cloudy · feels like +67°
The day is 2 min shorter than yesterday.
Sunshine hours count direct sun only — cloud cover cuts it, so it is shorter than daylight.
Geomagnetic fieldG1 geomagnetic storm, Kp 4.7
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.
What are solunar periods?Green check: this species was recorded here by GBIF. Species without a check may still occur in the waterbody.
Blue check: this species appears as a catch in reports for this waterbody.
