A southwesterly has held for the best part of three days, running warmer than the water (13°C air against 7°C water). Expect fish at the north-eastern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.
Winter carp on the fly is marginal — fish are lethargic and deep. Only worth trying on unusually mild, sunny days when carp push into warming shallows. Sight-fishing only. Polarised glasses essential.
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
As water cools through September and October, carp shift away from surface feeding and concentrate on building reserves before winter. They cruise subsurface along weed edges, dam faces and the deeper sections of margins, occasionally feeding on invertebrates. Bottom bugs and nymphs dropped precisely in the path of cruising fish work best. Surface flies become unreliable once water temperature drops below 12°C. Approach cautiously — autumn carp in clear water are easily spooked.
A reasonable day here, though temperature isn't quite in the sweet spot.
The park lake is one of the city’s better-known urban carp venues, with fishing explicitly listed among the park’s permitted activities. Carp are the main draw, especially when warm weather brings fish into shallow margins. An accessible, low-barrier entry point for anyone curious about sight-fishing carp on fly — but always check current park and water-condition notices before travelling.
Quirky urban carp-on-the-fly option in Madrid.
