Years ago, fishermen in Peru and Ecuador in South America noticed that during some winters, the ocean became warmer than usual. The fishermen gave the warmer water a name. They named it "El Niño." In Spanish, El Niño means "the little boy." When the ocean became warmer, the fishermen noticed that they could not catch as many fish. The fishermen also noticed that the amount of rain increased.
During an El Niño or La Niña year, parts of the Pacific Ocean warm and make changes in weather around the world. The effects of El Niño or La Niña cause changes in rainfall and temperature as far away as the United States and Australia. Usually, El Niño comes every 3 to 5 years, and La Niña less frequently.
