Where are the wettest parts of Spain?

The wettest parts of Spain are the northern regions, such as Galicia, Asturias, Cantabria, and the Basque Country. These areas receive an average of over 1,000 mm of precipitation per year, with some areas receiving over 2,000 mm. The high levels of precipitation in these regions are due to their proximity to the Atlantic Ocean and the prevailing westerly winds that bring moisture-rich air from the ocean over the mountains. These areas are characterized by lush vegetation and green landscapes, with many rivers and lakes. The combination of high humidity, rainfall, and mild temperatures creates a favorable environment for plant growth.
