Lake Porth Creek (Cornwall) — a popular fishing spot. About 1.7 km² in area. Nearby towns: Falmouth, Penryn and Truro. See when the bite is best: hourly fish activity for the days ahead, computed from the weather, pressure, and season.
Cloudy: 15–19 °C
The shoreline is heavily indented — bays, points and spits. Look for pike at the mouths of the bays and on the drop-offs behind the points. Larger than 15 of the 16 waters nearby.
The wind builds its wave along the north — south axis — 3 mi of open water; along west — east there is only 1 mi. When it runs down the main axis, the calm water sits against the bank it blows from, while the wave and the silt go to the far one — and the fish follow them there to feed.

Chum one spot near a drop-off and wait for fish to arrive — don't chase them.
Porth Creek — Friday, September 18
The bite is weak — fish are sluggish. Weather is steady, with no sharp swings — fish behave predictably. Peak 11:00–16:00.
The computed water temperature is around 15 °C — inside the 14–26 °C comfort range for Bleak, so baseline activity is high.
Bleak feeds by day — between sunrise and sunset; their times are in the sun-and-moon card above.
Pressure is flat: it moves no more than 1 hPa 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.
September is a slow season for Bleak: the best months fall at another time of year.
These are the same values the bite curve above was computed from. How the forecast works
Cloudy · feels like +15°
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.
