Despite its modest altitude, form a very peculiar landscape, where rounded elevations, the hills are cut by a dense river network, consisting mostly of temporary waterways. The relief is for this reason fairly rough at several points.

The  Serra do Caldeirão has considerable climatic influence. It constitutes a physical barrier to the passage of the cold winds of the North and Northwest quadrant of depressions, contributing to the existence of a Mediterranean climate in the Algarve coast, with low annual rainfall and mild temperatures in winter. On the other hand, is also a condensation barrier for winds wet South quadrant.

The average annual rainfall varies: in the higher areas of the municipality of Loulé are greater than 800 mm per year, but as we approach the border with Spain to the east (Guadiana valley), go down until they are below 500 annual mm in the regions of the Algarve Northeast.
