Spain's carp fishing season is broadly year-round, though the intense summer heat (July–August) can push fish very deep and make daytime sport difficult on exposed reservoirs. The best carp fishing windows are spring (March–June) when water temperatures rise and fish feed heavily before spawning, and autumn (September–November) when temperatures cool and fish feed up for winter. The large Extremadura reservoirs (Cijara, Orellana, Garcibáñez) and Aragón's Embalse de Mequinenza are particular highlights for UK specimen hunters. Night fishing is essential in summer months — confirm the rules on your licence before setting up after dark.
