The warning comes at a time when excessive climate has already turn into a serious concern throughout a number of elements of the world. From intense warmth to heavy rain and floods, uncommon climate patterns have repeatedly disrupted regular life this yr.

For India, the growing El Niño may affect temperatures and rainfall patterns within the months forward. Nevertheless, a really sturdy El Niño doesn’t robotically imply the identical climate impacts in every single place, and its impact on India can even rely upon different ocean and atmospheric situations.
Why WMO is frightened about this El Niño
WMO forecasts counsel an “exceptionally excessive chance of almost 100%” that El Niño situations will proceed by way of February 2027. The organisation mentioned this degree of confidence displays sturdy settlement between totally different forecasting methods.
The occasion can also be anticipated to turn into stronger earlier than reaching its peak in direction of the top of 2026. Its affect may proceed into 2027 even after the Pacific Ocean reaches its most warming.
UN Secretary-Common António Guterres described the phenomenon as an El Niño that’s successfully being “supersized”, warning that rising ocean temperatures are growing the dangers from excessive climate.WMO Secretary-Common Celeste Saulo has additionally referred to as for stronger preparation, saying governments and communities must act forward of doable disruptions to agriculture, water, well being, vitality and catastrophe administration.
Pacific Ocean temperatures are unusually excessive
One of many clearest indicators of the strengthening El Niño is the fast warming of the tropical Pacific.The Niño 3.4 index, a broadly used measure of sea floor temperatures within the central-eastern equatorial Pacific, averaged 1.5°C above regular throughout Might-July 2026. In July, the anomaly reached round 2°C.

Weekly readings then climbed additional, reaching roughly 2.2°C to 2.6°C above common between late July and mid-August. The bizarre heat isn’t restricted to the ocean floor. Throughout July and early August, temperatures under the floor have been greater than 8°C above common in some areas. These situations are offering sturdy assist for a continued and intensifying El Niño.
Will India actually haven’t any winter this yr?
The growing climate sample has raised questions on whether or not India may see a weak winter in 2026-27. A powerful El Niño can alter atmospheric circulation and shift temperature and rainfall patterns throughout distant elements of the world. WMO’s newest seasonal forecast factors to a broad threat of above-normal temperatures throughout nearly all land areas throughout September-November 2026.
However, the depth of El Niño alone doesn’t decide what occurs in each nation. Native climate situations are influenced by a number of different components, together with the Indian Ocean and Atlantic Ocean. For India, the ultimate winter outlook will due to this fact rely upon how these totally different local weather drivers work together.
India faces a sophisticated climate outlook
The strengthening El Niño is especially vital for India as a result of adjustments in Pacific Ocean situations can have an effect on large-scale atmospheric circulation and the nation’s rainfall patterns.
The WMO has additionally highlighted the anticipated growth of a optimistic Indian Ocean Dipole (IOD) throughout the September-November interval. Its seasonal imply is forecast at round 0.9°C for September-October-November 2026.
On the similar time, elements of the tropical Atlantic are additionally anticipated to stay hotter than regular. These extra components can strengthen, weaken or alter the standard results related to El Niño. That’s the reason a single El Niño-based forecast can’t be used to foretell India’s climate months upfront with certainty.
Warmth, drought and floods may all stay a threat
A really sturdy El Niño will increase the chance of great adjustments in rainfall, temperatures and atmospheric circulation world wide. Some areas may expertise extended dry situations, growing strain on water provides and elevating the danger of wildfires. Different areas may see episodes of unusually heavy rainfall and flooding.
That distinction is among the greatest challenges posed by large-scale local weather occasions. The identical world local weather phenomenon can produce very totally different outcomes relying on location and season.
WMO’s September-November outlook already signifies widespread possibilities of above-normal temperatures, whereas rainfall situations are anticipated to fluctuate significantly from one area to a different.
Why world warming makes the state of affairs extra critical
El Niño itself is a naturally occurring a part of the Earth’s local weather system. It develops when floor waters within the central and japanese equatorial Pacific turn into unusually heat. Nevertheless, it’s unfolding in opposition to a background of long-term world warming.
The mix implies that particular person El Niño occasions can happen on high of an already hotter local weather. This raises issues about excessive temperatures and different weather-related dangers.
The 2023-24 El Niño interval coincided with exceptionally excessive world temperatures, with 2024 turning into the warmest yr on document. The priority now could be that the growing 2026 occasion may add additional strain to an already warming local weather system.
What occurs subsequent?
El Niño often develops between March and June and reaches its strongest section between November and February. Its results on world temperatures can proceed even after the height of ocean warming.That timing makes the following a number of months significantly vital.
WMO says forecasts may give governments, companies, humanitarian businesses and communities helpful time to organize for potential disruptions. The organisation is looking for early motion quite than ready for excessive climate occasions to happen.
For India, the important thing takeaway isn’t that winter will disappear fully, however that the standard climate sample may turn into extra unpredictable as a really sturdy El Niño interacts with different local weather drivers.
The approaching months will present how a lot the Pacific warming interprets into adjustments over the Indian subcontinent.
