El Niño/La Niña Update (June 2023)
- El Niño develops in tropical Pacific
- It will likely fuel further global temperature increase
- El Niño affects weather and storm patterns in different parts of the world
- Early warnings and early action to save lives and livelihoods
The tropical Pacific is currently experiencing El Niño conditions as a result of rapid and substantial changes in oceanic conditions observed in recent months. According to the latest predictions from the WMO Global Producing Centres of Long-Range Forecasts, there is a 90% probability of the El Niño during the second half of 2023 with only a 10% chance of weakening to an ENSO-neutral state.
The likelihood of La Niña development is negligible. National Meteorological and Hydrological Services (NMHSs) will closely monitor the evolution of El Niño conditions and the associated impacts on temperature and precipitation at national and local level. WMO will provide updated outlooks during the coming months as needed.
About the El Niño/La Niña Updates series
The El Niño/La Niña Update provides analysis of the current conditions and evolution of the status of the El Niño-Southern Oscillation phenomenon. These include detailed information on sea surface and subsurface temperature anomalies, atmospheric circulation, cloudiness and rainfall patterns. The Update is prepared through a collaborative effort between WMO and the International Research Institute for Climate and Society, with contributions from experts worldwide. The El Niño/La Niña Update is crucial for governments, humanitarian and disaster risk agencies, and policymakers to prepare for climate-related impacts and to provide guidance for meteorologists worldwide to refine regional predictions.
