WMO Warns: Strong El Niño and Extreme Weather Likely This Year
The World Meteorological Organization (WMO) has issued a warning about a high likelihood of a strong El Niño developing this year, which is expected to intensify extreme weather events globally. Climate change is predicted to amplify these effects, leading to more severe heatwaves, droughts, and floods. India is particularly vulnerable, with expectations of below-average monsoon rainfall.
Key Highlights
- WMO predicts strong El Niño with 80-90% certainty for 2026.
- Climate change will intensify El Niño's extreme weather impacts.
- Global temperatures to rise, increasing heatwaves and droughts.
- India's monsoon likely to be below average due to El Niño.
- Prepare for disruptions in rainfall, agriculture, and water resources.
- El Niño could make 2027 the hottest year on record.
The World Meteorological Organization (WMO) has issued a significant warning regarding the high probability of a strong El Niño event developing in the current year, 2026, with major implications for global weather patterns and the intensification of extreme weather events. The UN weather body indicates an 80% chance of El Niño developing between June and August 2026, and a 90% probability that it will persist until at least November, marking a clear signal of the phenomenon's return. This outlook has raised international concerns as climate change is expected to amplify El Niño's effects, potentially leading to more severe heatwaves, droughts, floods, and other weather-related disasters worldwide.
According to the WMO, there is a concern that this year's El Niño could be stronger than usual, with some climate models suggesting a 'strong' event defined by sea surface temperatures in the eastern Pacific rising at least 1.5 degrees Celsius above average. The scientific community underscores that while climate change may not directly increase the frequency or intensity of El Niño patterns, it significantly exacerbates the associated impacts. Piers Forster, Professor of Physical Climate Change at the University of Leeds, noted that El Niño events, against the backdrop of ongoing climate change, become 'more intensified and more impactful'. Global temperatures have already risen by approximately 1.3 degrees Celsius since pre-industrial times due to greenhouse gas emissions, setting the stage for more pronounced and hazardous weather phenomena.
The combination of El Niño and climate change could potentially make 2027 the hottest year on record, surpassing the previous record set in 2024, which was also classified as a strong El Niño year. The WMO Secretary-General, Celeste Saulo, emphasized the need to prepare for a potentially strong El Niño that will 'exacerbate drought and heavy rainfall and increase the risk of heatwaves both on land and in the ocean'. UN Secretary-General António Guterres further urged the world to treat it as an 'urgent climate warning,' calling for accelerated climate action, an end to fossil fuel dependency, a shift to renewables, protection for vulnerable populations, and robust early warning systems.
For India, the implications of a developing strong El Niño are particularly significant. The India Meteorological Department (IMD) and regional climate forums, supported by WMO data, indicate a high likelihood of below-average rainfall during the June-September 2026 southwest monsoon season across much of South Asia, with the strongest signal over central regions. This is a major concern as India's southwest monsoon provides nearly 70% of the country's annual rainfall, serving as a lifeline for agriculture, drinking water, and the overall economy.
Historical patterns reveal that strong El Niño events often spell trouble for India's monsoon, leading to drier conditions in southern Asia. For millions of farmers dependent on rain-fed crops like rice, maize, pulses, and cotton, this could translate to lower soil moisture, reduced harvests, and increased costs. Past El Niño years have frequently resulted in drought-like conditions in various parts of the country, driving up food prices and negatively impacting rural incomes. Moreover, intensified heatwaves are also anticipated, adding stress on human populations, livestock, and power grids. While a strong El Niño may persist into early 2027, meteorologists note that such events typically weaken substantially before the subsequent monsoon season, potentially sparing India's 2027 rainy season from its peak effects. However, immediate preparedness for the 2026 monsoon remains critical.
Global weather agencies are urging countries to prepare for significant disruptions to rainfall patterns, agriculture, and water resources. The developing El Niño is a global phenomenon with varied regional impacts, bringing heavier rains to some areas like Southern South America and parts of Central Asia, while leading to drier conditions in Central America and Australia. This global climatic event underscores the urgent need for international cooperation and national preparedness strategies to mitigate its far-reaching consequences.
Frequently Asked Questions
What is El Niño and why is it a concern for 2026?
El Niño is a natural climate pattern characterized by the periodic warming of sea surface temperatures in the central and eastern Pacific Ocean, typically lasting 9 to 12 months. It's a concern for 2026 because the WMO predicts an 80-90% chance of a strong El Niño developing and persisting, which historically leads to disrupted rainfall patterns, higher global temperatures, and extreme weather events worldwide.
How does climate change influence El Niño's impact?
While climate change does not necessarily increase the frequency or intensity of El Niño itself, it significantly amplifies its effects. Global warming, driven by greenhouse gas emissions, means that when an El Niño occurs, the associated extreme weather phenomena such as heatwaves, droughts, and heavy rainfall become more severe, intense, and impactful.
What are the potential consequences of a strong El Niño for India?
For India, a strong El Niño typically spells trouble for the southwest monsoon, which is vital for the country's agriculture and water resources. The WMO has indicated a high likelihood of below-average monsoon rainfall across much of South Asia, particularly central regions, leading to potential droughts, lower crop yields, increased food prices, and intensified heatwaves.
Which regions globally are most affected by El Niño?
El Niño affects regions differently. Historically, it brings heavier rainfall to areas like Southern South America and parts of Central Asia. Conversely, Central America and Australia often experience drier conditions. Globally, it contributes to higher temperatures and can influence hurricane activity and the intensity of heatwaves.
What actions are being urged in response to the WMO warning?
The WMO and UN Secretary-General are urging immediate preparedness for El Niño's impacts. This includes accelerating climate action, transitioning away from fossil fuels to renewable energy, protecting vulnerable populations, and strengthening early warning systems to mitigate the devastating speed and reach of its effects.
