What will El Niño bring where you live? Maps show its wide-reaching impacts.
El Niño is reshaping weather patterns across the globe, with effects varying sharply by region. The phenomenon is bringing warmer temperatures to parts of North America and Europe, while intensifying rainfall in Southeast Asia and the Pacific. Australia's experiencing drought conditions in some areas, even as other regions see increased precipitation. This cycle occurs irregularly—the last significant El Niño ended in 2016—and typically lasts eighteen months to two years. Scientists are tracking how these shifts affect agriculture, water supplies, and storm systems through the coming seasons, with particular attention to tropical regions where impacts tend to be most severe.
