TL;DR
Scientists warn that this upcoming Super El Niño could be more intense than any on record since 1950, potentially causing extreme weather worldwide. While forecasts indicate a very strong event, the exact severity remains uncertain due to climate change influences.
Scientists now warn that this Super El Niño could be the strongest on record, with some models indicating it might surpass the intensity of the 2015-2016 event. A ‘Super El Nino’ could be on its way. This development is critical because of its potential to trigger widespread extreme weather patterns worldwide, including floods, droughts, and heatwaves.
Over recent months, ocean temperatures in the tropical Pacific have reached record highs for this time of year, signaling a rapid strengthening of El Niño conditions. Multiple computer models now project that this event could be stronger than previous ones, possibly exceeding the intensity of the 2015-2016 Super El Niño, which was among the most severe in recent history.
Experts from institutions like Columbia University and climate scientists such as Zeke Hausfather have noted a clear trend toward a more intense El Niño, with the likelihood of it becoming a record-breaking event increasing each month. The World Meteorological Organization (WMO) has issued warnings that El Niño conditions are already underway and are expected to intensify quickly between July and September, with broad implications for global weather patterns.
However, the exact strength of this El Niño remains uncertain, as it depends on how climate change influences ocean and atmospheric interactions. The current backdrop of record-high global sea surface and air temperatures complicates predictions, and some impacts of past El Niño events, such as specific teleconnection patterns, have not fully materialized this year.
Implications of an Unprecedented Super El Niño
This event could have profound impacts on global weather, agriculture, and economies. Stronger El Niño events are associated with increased risks of flooding, drought, and heatwaves across multiple continents. For example, regions like Southeast Asia and the U.S. could experience severe droughts or intense storms, disrupting food supplies and infrastructure. The WMO has called for governments and agencies worldwide to prepare for these potential disruptions, emphasizing the need for emergency planning and resource management.
Additionally, the ongoing record warmth due to climate change may amplify the effects of this El Niño, potentially leading to more extreme and prolonged weather events than historically observed. The combination of climate change and an exceptionally strong El Niño could accelerate global temperature increases and complicate mitigation efforts.

Historical and Scientific Context of Super El Niño Forecasts
El Niño is a natural climate cycle characterized by warmer-than-normal ocean temperatures in the tropical Pacific, which influence weather globally. Historically, only a handful of El Niño events have been classified as ‘Super,’ with the last notable one occurring in 2015-2016. Recent climate models have indicated that this upcoming El Niño could be even more intense than those past events, with some projections suggesting it could surpass the intensity of any event since 1950.
Scientists have been closely monitoring ocean temperature patterns and atmospheric conditions, noting that ocean temperatures in the Pacific have been record warm for this time of year. The last El Niño, in 2023-2024, was less intense and did not produce some typical teleconnection effects, but the current forecasts suggest a significantly stronger event this time. The WMO’s latest statements reflect a consensus that rapid intensification is likely, driven by the current warming trend and oceanic conditions.

Uncertainties in El Niño’s Future Strength and Impact
While models indicate a very strong El Niño, the exact peak intensity and regional impacts remain uncertain. Climate change’s influence on ocean-atmosphere interactions introduces unpredictability, and the full extent of how this event will compare to past super El Niños is still unclear. Additionally, the potential for climate change to modify typical teleconnection patterns complicates impact predictions.

Monitoring and Preparing for the Peak of El Niño
Scientists and meteorological agencies will continue to monitor ocean and atmospheric conditions closely over the coming months. The WMO and other organizations are expected to issue updated forecasts as the event approaches its peak in late fall to early winter. Governments worldwide are advised to prepare for extreme weather events, including floods, droughts, and heatwaves, and to coordinate humanitarian responses as needed.

Key Questions
How likely is this El Niño to break previous records?
Based on current model projections, there is a high probability that this El Niño could surpass previous strongest events, including the 2015-2016 super El Niño, but exact strength remains uncertain.
What regions are most at risk from this El Niño?
Regions such as Southeast Asia, Australia, the western Pacific, parts of North and South America, and Africa are expected to experience significant impacts, including increased droughts, floods, and heatwaves.
Could climate change alter the impacts of this El Niño?
Yes, the ongoing global warming trend may amplify the effects of this El Niño, potentially leading to more severe and prolonged weather disruptions than typical for past events.
When will the peak impacts of this El Niño be felt?
The strongest impacts are expected during the Northern Hemisphere’s winter months, from late fall through early spring.
What should governments and individuals do now?
Preparedness measures, including emergency planning and resource allocation, are advised as agencies monitor the evolving situation closely.
