Super El Niño 2026–27: Pakistan Winter Forecast and Global Weather Impact

A powerful El Niño has developed in the tropical Pacific, and climate agencies now expect it to become one of the strongest events in the modern record. The World Meteorological Organization (WMO) says the event is likely to intensify to very strong levels, peak toward the end of 2026 and persist through February 2027.
The International Research Institute for Climate and Society (IRI) at Columbia University has also reported unusually strong agreement across its 22-model ensemble. Its September 21 assessment showed Niño 3.4 reaching about +3.0°C by mid-September, with the models indicating that very strong El Niño conditions could continue through the winter of 2026–27.
This matters because the event is developing on top of an already exceptionally warm global climate.
Why This El Niño Is Different
According to the Copernicus Climate Change Service (C3S), August 2026 was the warmest August on record globally, with an average surface air temperature of 16.96°C. Global sea-surface temperatures outside the polar regions also reached a record August level.
That background does not mean every country will set a temperature record. Weather varies from region to region.
But it does mean that a strong natural warming event such as El Niño is developing within a climate system that is already unusually warm.
El Niño itself is a natural process that redistributes heat from the tropical Pacific Ocean into the atmosphere. When it occurs alongside long-term human-caused warming, the combined climate conditions can increase the likelihood of unusual temperature extremes and major shifts in rainfall.
WMO's seasonal outlook has pointed toward widespread above-normal temperatures and significant changes in rainfall patterns as the Pacific event strengthens.
What Is Driving the 2026–27 Event?
El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO), a recurring climate pattern involving the tropical Pacific Ocean and atmosphere.
During El Niño, sea-surface temperatures become much warmer than normal across the central and eastern equatorial Pacific. This changes trade winds, atmospheric circulation and tropical rainfall, which then affects weather patterns far beyond the Pacific.
Scientists track its strength using several Niño indices, including Niño 3.4.
In its September 10 diagnostic discussion, NOAA reported that sea-surface temperature anomalies in parts of the eastern equatorial Pacific had exceeded +3.0°C. The August Niño 3.4 index reached +1.8°C, while Niño 3 and Niño 1+2 were even warmer. NOAA gave a greater than 90% chance of a very strong El Niño during the Northern Hemisphere fall and winter of 2026–27.
IRI's September 21 assessment showed that the event had strengthened further. The weekly Niño 3.4 value centered on September 16 reached about +3.0°C, while the August monthly value was +2.52°C. All 22 forecast models pointed toward continued strengthening, and IRI said the event could rank among the strongest El Niño events on record.
This is why the term "Super El Niño" is increasingly appearing in media coverage.
It is useful shorthand for an exceptionally intense event, but it is not an official scientific classification. WMO and NOAA use terms such as "very strong" or "exceptionally strong" El Niño.
What Could This Mean for Pakistan?
For Pakistan, the relationship with El Niño is not as simple as saying "El Niño means hot and dry everywhere."
Pakistan's weather is influenced by several climate systems at the same time, including western disturbances, the Indian Ocean Dipole (IOD), snow cover over Eurasia and the North Atlantic Oscillation (NAO).
ENSO is an important factor, but it is not the only one.
An early Pakistan-focused outlook published by Space4Climate in June 2026 linked the emerging El Niño with a higher risk of below-normal rainfall and warmer conditions during parts of the 2026 season and suggested a warmer-than-normal winter tendency. However, that outlook was an early assessment and should not be treated as a final December 2026–February 2027 forecast.
This distinction is particularly important for northern Pakistan.
Winter precipitation there depends heavily on western disturbances, which transport moisture into northern and western parts of the country and are responsible for much of the winter rain and mountain snowfall. Research involving Pakistan Meteorological Department scientists has shown that ENSO and NAO can influence winter precipitation, but their interaction with western disturbances determines the actual outcome in many years.
So a strong El Niño does not automatically mean a dry winter across all of Pakistan.
In some weather setups, especially when other large-scale circulation patterns change, parts of northern Pakistan can receive significant winter precipitation even during a warm ENSO phase.
What could matter most for Pakistan this winter?
Agriculture: Below-normal rainfall in some areas could increase dependence on irrigation and stored water.
Water resources: Reduced mountain snowfall, if it occurs, could affect later seasonal water availability and reservoir inflows.
Energy demand: A warmer average winter would not eliminate the possibility of short-lived cold spells when western disturbances or continental air masses become active.
Northern areas: Snowfall will depend heavily on the frequency, track and strength of western disturbances rather than on El Niño alone.
The key message is preparedness, not panic. Long-range climate signals are useful for identifying risk, but local and short-range weather forecasts become much more important as winter approaches.
Pakistan's Winter Signal Is Not a One-Factor Forecast
This is where the El Niño discussion becomes more complicated.
Historical research on northern Pakistan has found important connections between ENSO, NAO and winter precipitation. One Pakistan-focused study found that positive NAO conditions combined with warm ENSO conditions can be associated with increased precipitation over parts of the northern highlands because of their influence on westerly circulation and western disturbances.
Other research has shown that climate drivers do not affect every part of Pakistan in the same way.
That means the country's winter forecast should not be reduced to a single sentence such as "strong El Niño equals less rain."
For farmers, water managers and communities in the northern mountains, the more useful question is how El Niño interacts with the other circulation systems that control individual winter storms.
Global Impacts: From Asia to the Americas
El Niño creates a geographic patchwork of impacts.
WMO has warned that a very strong event can produce major shifts in rainfall and temperature patterns around the world, increasing the risks of drought, flooding and extreme heat in different regions.
Southeast Asia is among the regions being watched closely because strong El Niño conditions can favor hotter and drier conditions in parts of the region. That can place pressure on agriculture, water supplies, forests and fisheries.
Meanwhile, parts of South America and the southern United States can experience wetter-than-normal conditions during strong eastern-Pacific El Niño events.
But the pattern is never identical from one event to another.
Another Climate Driver Is Joining the Picture
El Niño is also developing alongside changes in the Indian Ocean Dipole.
WMO's September seasonal outlook projected a positive IOD phase, with the ensemble mean around +0.9°C for September–November 2026. The IOD can reinforce or modify typical El Niño impacts, particularly across South Asia, East Africa and Australia.
This interaction is one reason seasonal climate forecasts are expressed in probabilities rather than certainties.
A forecast can indicate that the likelihood of a particular temperature or rainfall pattern is higher than normal without guaranteeing that it will happen.
Why Food Markets Are Watching Closely
The economic effects of a very strong El Niño can extend far beyond the places directly experiencing drought or heavy rain.
Agricultural markets are especially sensitive to extreme weather.
A production shortfall in a major exporting country can affect international prices for food and agricultural commodities even when weather conditions are normal somewhere else.
Rice, wheat, palm oil and other crops are therefore among the products being watched as the event strengthens.
The impact will not be uniform. Wetter conditions can benefit some crops in some regions, while heat, drought or excessive rainfall can reduce production elsewhere.
That makes the economic consequences dependent on geography, crop type, inventories and the ability of governments and traders to adjust supply.
August's Global Heat Record Adds Another Layer
The timing of this El Niño is particularly important because global temperatures are already unusually high.
Copernicus reported that August 2026 reached a global average surface temperature of 16.96°C, making it the warmest August in its ERA5 record. The month was also about 1.65°C above the estimated 1850–1900 pre-industrial level.
That does not mean El Niño alone caused the August record.
The broader warming trend and unusually warm ocean conditions were also important factors.
But it shows the environment in which the current El Niño is developing.
What Will Determine How Strong the Event Becomes?
Three factors will be particularly important.
Peak intensity: Whether the Niño 3.4 anomaly remains above the levels associated with a very strong event and how long the extreme warmth persists.
Location of the warmest water: Whether the strongest warming remains concentrated in the eastern Pacific or shifts toward the central Pacific can change the regional weather response.
Interaction with other climate systems: The evolution of the IOD, NAO, western disturbances and other atmospheric patterns will influence the weather actually experienced across South Asia and other regions.
WMO currently expects El Niño to strengthen further and peak toward the end of 2026, while its forecasts show an exceptionally high likelihood that the event will persist through February 2027.
Questions Readers Are Asking
Is "Super El Niño" an official scientific term?
No.
"Super El Niño" is media shorthand for an unusually intense event. Official agencies such as WMO and NOAA use classifications including strong, very strong or exceptionally strong El Niño.
Will El Niño make all of Pakistan hotter and drier during winter 2026–27?
Not necessarily.
Current climate guidance supports a warmer-risk background, but Pakistan's winter rainfall and snowfall are strongly influenced by western disturbances and other atmospheric circulation patterns.
Could northern Pakistan receive less snow?
It is a possibility, particularly if western disturbances are weak or follow less favorable tracks.
But it cannot be determined from El Niño alone.
Could strong western disturbances still produce heavy snowfall?
Yes.
The presence of a strong El Niño does not prevent western disturbances from producing significant rain and snow. The interaction between ENSO, NAO, jet-stream behavior and available moisture is more important for individual winter events.
Will El Niño make 2026 the hottest year on record?
It could contribute to unusually high global temperatures, but the final ranking of 2026 depends on temperatures across the entire year.
August 2026 already set a record for the warmest August in the Copernicus ERA5 dataset, but that alone does not establish the ranking of the full year.
The Winter Outlook From Here
The biggest change since this article was first prepared is that El Niño has strengthened faster and more dramatically than earlier forecasts suggested.
By mid-September, IRI was already observing a Niño 3.4 value around +3.0°C, while WMO was describing the event as likely to become very strong and persist into early 2027.
For Pakistan, that raises the importance of seasonal preparation, but it does not justify treating a dry or unusually warm winter as certain.
The most important information will come from updated regional forecasts as December approaches.
For northern Pakistan in particular, the frequency and strength of western disturbances will remain a major factor in determining whether the winter is relatively dry, snowy, wet or highly variable.
Globally, the combination of a very strong El Niño with exceptionally warm oceans creates a higher-risk environment for temperature and rainfall extremes.
The event is therefore important not because every part of the world will experience the same weather, but because it can reorganize atmospheric patterns across many regions at the same time.
The Broader 2026–27 Climate Risk
This El Niño is developing in a climate system where ocean and land temperatures are already unusually elevated.
That does not mean every extreme event during the coming months will be caused by El Niño. Attribution has to be assessed event by event.
What the current forecasts do show is a heightened likelihood of major shifts in temperature and precipitation patterns as the Pacific warming strengthens.
For Pakistan, the practical focus should remain on water availability, agricultural planning, winter precipitation and early warnings for extreme weather.
For the wider world, attention will increasingly turn to drought, flooding, heat, wildfire risk, food production and the economic effects of weather-sensitive commodities.
The coming months will reveal how closely the actual regional impacts follow the current model projections.
For now, the scientific signal is unusually clear: El Niño is strong, strengthening further, and likely to remain an important global climate driver into early 2027.
