Torre-Pacheco municipality is located in the Campo de Cartagena region. Cabezo Gordo is one of its highest hills, at 312 metres above sea level. It has no rivers with a permanent water flow, although during rainy periods streams in several arroyos flow into coastal saltwater lagoon the Mar Menor. Soil in the area mainly comprises sedimentary materials (loam, sandstone and limestone).

Torre-Pacheco is semi-enclosed by mountains. To the north lie the Columbares, Carrascoy, El Puerto, Escalona and Altalona ranges, and to the south the ranges of La Unión, Roldán, La Muela, Las Victorias and Cartagena.

The surrounding mountains have a significant influence on the semi-arid, Mediterranean climate of the municipality. Rainfall is usually below 300 millimetres, but when it occurs rain is often torrential. Highest rainfall occurs in autumn and spring, and the rainiest months are October and April. Temperatures are generally high but can appear mild because of sea breezes. Winters are mild.

Human activity has had a major impact on the territory, resulting in particular from the mechanization of local agriculture in the 1950s and 1960s.
