Peru's climate can be divided into two seasons - wet and dry - though this varies, depending on the geographical region. The coast and western Andean slopes are generally dry, with the summer falling between December and April; during the rest of the year, the garúa (coastal fog) moves in and the sun is rarely seen. In the Andes, the dry season is from May to September, while the wet season takes up the remainder of the year. On the eastern slopes of the Andes, the drier months are similar to the highlands, though the wet season (January to April) is more pronounced.
