What gives this region a special character is its geography and climate. It is due to its special climatic conditions that this valley has become the birth of one of the world’s most well-known drinks, port wine.
The Douro has its own micro-climate. The long mountain range along the west of this region protects the valley from the cold and humid winds that sweep in from the Atlantic, creating drier conditions than along the coast, but also colder winters and warmer summers.
Throughout the valley, you’ll find that the temperature changes slightly. The parts of the valley facing South have slightly higher air temperatures than those facing North. This gives the Douro its metamorphic aspect; changing as you drive further and further into its more arid lands in the east and greener areas in the western part.
