The desert region of Chile is the driest part of South America. The westerly winds carrying moisture shed their moisture on the western parts of the Andes, thus leaving the eastern portions of mountains with negligible rainfall. The cold Peru Current is responsible for the dry coastal parts of Peru as well as northern Chile. The cold current is less likely to hold moisture than warm currents.
The highest temperatures of South America have been recorded in Gran Chaco in Argentina, with temperatures going up to 110°F. The wettest place on the continent is Quibdo in Colombia that receives an annual rainfall of 350 inches or 890 centimeters.
The four regions of South America which receive heavy rainfall are the Amazon River Basin, coastal parts of French Guiana, Guyana and Suriname, and the southwestern coasts of Chile, Colombia, and Ecuador.
A unique feature of South America's climate is the El Nino. Every two to seven years the cold dry Peru Current weakens and warm waters from the south rush along the coast in a southward direction. The El Nino affects the climate of South America and causes heavy rainfall in the dry parts of South America.
The countries in the northern South America such as Colombia, Ecuador, and Venezuela have more constant high temperatures and high rainfall throughout the year. The countries in southern South America such as Chile and Argentina have lower temperatures with less rainfall.
