Köppen Climate Classification Chart of Portugal mainland for the 1971-2000 period indicating that, for most of the continental territory, climate is temperate, type C, verifying the subtype Cs (temperate climate with dry summers) and the following varieties "Csa": temperate climate with hot, dry summers in the interior regions of Douro valley (part of Bragança district), as well as in the south regions of the Montejunto-Estrela mountain system (except on the west coast of Alentejo and Algarve); "Csb": temperate climate with dry and mild summer in almost all regions of the North Montejunto-Estrela mountain system and in the west coast regions of Alentejo and Algarve. A small region of Alentejo, in the district of Beja, has Arid Climate - Type B Subtype BS (steppe climate), variety BSk (cold steppe climate of the mid-latitude).
