El Niño is a climate pattern that describes the unusual warming of surface waters along the tropical west coast of South America. El Nino has an impact on ocean temperatures‚ the speed and strength of ocean currents‚ the health of coastal fisheries‚ and local weather from Australia to South America. El Niño events occur irregularly at two- to seven-year intervals. However‚ it is not a regular cycle‚ or strictly predictable in the sense that ocean tides are. El Niño has long been recognized
