There is a 60% likelihood of an El Niño being fully established between June and August, increasing to 75-80% for the October to December period, according to an El Niño Update issued by the World Meteorological Organization (WMO).
Based on advice from National Meteorological and Hydrological Services, many Governments have already started preparing for the arrival of El Niño, which is associated with regional-scale drought and flood situations in different parts of the world and has a warming influence on global average surface temperatures.
El Niño is characterized by unusually warm ocean surface temperatures in the central and eastern tropical Pacific, coupled with typical atmospheric circulation patterns. It is a natural phenomenon with a recurring interval of 2-7 years and has a major impact on the climate around the world. The last El Niño was in 2009/2010.
Tropical Pacific Ocean temperatures have recently warmed to weak El Niño thresholds but atmospheric conditions (such as sea level pressure, cloudiness and trade winds) have remained neutral. This indicates that El Niño has not yet become fully established, as it essentially depends on the interaction between the ocean and the atmosphere. However, atmospheric patterns that are typical of a fully developed El Niño event on the basin-wide scale are still likely to appear, according to the WMO Update, which is based on consensus from experts around the world.
