- Free fishing
Water at 37.1°C — too warm to target pike today: poor sport, and where catch-and-release is legal (designated pre-2007 waters) warm water makes released fish die. Where it isn't, the official advice is to remove any fish caught from the water rather than return it. Either way, wait for cooler water.
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
- Comunidad de Madrid licence required
- Leisure use is heavy — check permitted fishing zones, seasonal restrictions, and any temporary closures around the swimming/boating areas.
A reasonable day here, though temperature isn't quite in the sweet spot.

- High temperatures may push fish deeper and reduce surface activity.
- Reservoir near full — settled fish across plenty of holding water.
