According to the latest updates from the WMO, the probability of El Niño conditions manifesting during the June-August 2026 period has reached a staggering 80 percent. Even more concerning is the long-term outlook, which indicates that the probability of this phenomenon persisting through at least November 2026 has surged to over 90 percent. While the exact peak intensity of the event remains under close observation by climatologists, the majority of advanced meteorological forecast models suggest that this iteration of El Niño will likely fall into the "moderate" category, with a significant potential to escalate into a "strong" event.
A Global Climate Emergency
The impending arrival of El Niño has prompted high-level warnings from the United Nations. "The science is clear: El Niño will be at our doorstep in the coming months with 90 percent certainty. The world must treat this as an urgent climate warning," stated UN Secretary-General António Guterres in an official communique released via the WMO. Guterres emphasized that the El Niño condition will inevitably exacerbate the existing pressures of global warming, leading to destructive impacts that transcend national borders. He called for a global response that matches the scale of the crisis, urging nations to implement climate actions that are commensurate with the looming threat.
The WMO’s observations conducted from late April to mid-May revealed that sea surface temperatures in the central-eastern equatorial Pacific are already hovering near the critical El Niño threshold. This surface warming is being fueled by exceptionally high temperatures beneath the ocean’s surface, which have been recorded at levels up to 6 degrees Celsius above the historical average. This massive reservoir of subsurface heat acts as a continuous energy supply, facilitating intensive and sustained warming at the surface. Furthermore, the Southern Oscillation Index (SOI), which tracks the atmospheric component of the El Niño-Southern Oscillation (ENSO) cycle, is now reported to be in alignment with the development of the phenomenon.
Understanding the ENSO Cycle and the Indonesian Context
El Niño and its counterpart, La Niña, represent the opposing phases of the El Niño-Southern Oscillation (ENSO), which is widely considered one of the most influential natural climate patterns on Earth. While each El Niño event is unique in its evolution, duration, and specific impacts, there are distinct global patterns that provide a roadmap for what to expect. Generally, El Niño is associated with increased rainfall in parts of southern South America, the southern United States, and Central Asia. However, for Southeast Asia—and Indonesia in particular—the phenomenon typically brings the opposite: significantly drier conditions and a heightened risk of severe, prolonged drought.
In Indonesia, the stakes are exceptionally high. The nation’s geography as an archipelagic state located between the Pacific and Indian Oceans makes it highly sensitive to shifts in sea surface temperatures. During El Niño years, the typical "warm pool" of water that sits around Indonesia shifts eastward toward the central Pacific. This shift results in reduced cloud formation and suppressed rainfall over the Indonesian maritime continent.
The Magnitude of Impact on Indonesia’s Agriculture and Economy
The primary concern for Indonesian authorities and citizens alike is the threat to food security. Indonesia’s agricultural sector, particularly rice production, is heavily dependent on the timing and volume of the monsoon rains. A moderate-to-strong El Niño can delay the planting season, cause crop failures, and deplete irrigation reservoirs. Historical data from previous strong El Niño events, such as those in 1997-1998 and 2015-2016, show a direct correlation between the phenomenon and a sharp decline in national grain output, often necessitating expensive emergency food imports.
Beyond agriculture, the risk of "Karhutla" (forest and land fires) becomes a critical national security issue. Dry conditions turn Indonesia’s vast peatlands into tinderboxes. When fires break out during El Niño years, they often become uncontrollable, producing a thick, toxic haze that blankets not only Indonesian provinces but also neighboring countries like Singapore and Malaysia. The 2023-2024 El Niño, which was ranked as one of the five strongest on record, contributed significantly to the global temperature records seen in early 2024 and underscored the fragility of regional air quality and public health.
Technical Classifications and the "Super El Niño" Debate
WMO Secretary-General Celeste Saulo has urged the global community to prepare for extreme weather events, including intense heatwaves on land and in the ocean. "We need to be prepared for the potential of a strong El Niño event, which will worsen droughts and heavy rainfall while increasing the risk of heatwaves," Saulo explained. She noted that the recent 2023-2024 cycle played a pivotal role in the record-breaking global temperatures observed recently.
Interestingly, the WMO has clarified its stance on terminology, specifically avoiding the colloquial term "Super El Niño." The organization maintains that such a term is not part of the standard operational climate classification, which strictly categorizes events as weak, moderate, strong, or very strong. This precision in language is intended to ensure that policy responses are based on scientific rigor rather than sensationalism.
The Climate Change Multiplier Effect
While there is currently no definitive scientific evidence that human-induced climate change increases the frequency of El Niño events, there is a consensus among climate scientists that global warming amplifies their effects. A warmer atmosphere can hold more moisture, but it also accelerates evaporation. This means that when El Niño-induced droughts occur, they are more intense and dehydrate the soil faster than they did in the pre-industrial era. Conversely, when El Niño causes rain in other regions, the resulting floods are often more catastrophic due to the increased moisture capacity of the warm air.
The interaction between the natural ENSO cycle and the steady upward trend of global temperatures creates a "double whammy" effect. "Seasonal forecasts and early warnings are essential for saving lives and reducing the impact on our economies and communities," Saulo concluded. The WMO’s emphasis on "Early Warnings for All" is a strategic initiative aimed at ensuring that even the most vulnerable communities in Indonesia and elsewhere have access to actionable climate data before disaster strikes.
Chronology of the Current Cycle
The current transition into El Niño follows a rare "triple-dip" La Niña that lasted from 2020 to early 2023. This prolonged La Niña period provided a temporary, slight cooling influence on global temperatures, yet 2023 still emerged as the hottest year on record due to the underlying greenhouse effect. As the Pacific transitioned out of La Niña in early 2023, temperatures began to climb rapidly.
- Late 2023 – Early 2024: A strong El Niño peaked, contributing to record-breaking monthly temperatures globally.
- April – May 2024: Observations showed a brief neutral phase, but subsurface ocean heat remained abnormally high.
- June – August 2026 (Projected): An 80% probability of El Niño conditions returning or intensifying.
- September – November 2026 (Projected): A 90% probability of sustained El Niño conditions, likely reaching moderate to strong intensity.
Implications for Policy and Infrastructure
For Indonesia, these warnings necessitate immediate cross-sectoral coordination. The Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG) has been working closely with local governments to monitor water levels in strategic dams and to prepare cloud-seeding operations (Weather Modification Technology) to fill reservoirs before the peak of the dry season.
The energy sector is also at risk. Indonesia relies on hydroelectric power for a portion of its renewable energy mix. Extended droughts lead to lower water levels in dams like Cirata and Jatiluhur, potentially forcing a shift back to coal-fired power plants to meet electricity demand, which in turn increases carbon emissions—a vicious cycle of climate impact.
Furthermore, the economic implications extend to inflation. As water becomes scarce and crops fail, the price of basic commodities, particularly rice and chili, tends to spike. This puts a significant strain on low-income households and can affect national economic stability.
The WMO’s warning serves as a clarion call for proactive adaptation. As the world approaches the mid-2020s, the convergence of natural climate variability and man-made warming is creating a new era of "extreme normals." For Indonesia, the message is clear: the time to bolster water management, fire prevention, and food stockpiles is now, before the heat of the Pacific makes its presence felt across the archipelago.
