 The cold-summer subtype of the Mediterranean climate ("Csc") is rare and predominately found at scattered high-altitude locations along the west coasts of North and South America.This type is characterized by cool summers, with fewer than four months with a mean temperature at or above , as well as with mild winters, with no winter month having a mean temperature below (or ), depending on the isotherm used).Regions with this climate are influenced by the dry-summer trend that extends considerably poleward along the west coast of the Americas, as well as the moderating influences of high altitude and relative proximity to the Pacific Ocean.
