What makes Grazalema the wettest place in Spain?
The Sierra de Grazalema has a special microclimate. We are in a place whose topography dictates it to be the rainiest site in Spain because it is the first high area which the humid sea winds hit after coming off the Atlantic. Winds driven across these lowlands warm up and then rise abruptly on meeting the mountain range, causing a cooling effect and cloud formation with precipitation. The natural inclines then guide water to flow rapidly into streams, rivers and arroyos (seasonally flowing streams that are dry during summer). Lower down this water is being reserved in man-made reservoirs to prevent its instant loss from the area.
