Super El Niño is coming: Why India may sweat like never before

Climate scientists are closely monitoring the Pacific Ocean as early signals suggest the possible development of a “Super El Niño” in the coming months — a powerful climate event that could significantly alter global weather patterns and push temperatures to new highs. If it materialises, the phenomenon could bring scorching heat, erratic rainfall and a weaker monsoon for India, raising concerns for agriculture, water supply and public health.

What is El Niño?

El Niño is a natural climate phenomenon linked to the El Niño–Southern Oscillation (ENSO) cycle, which involves periodic warming of sea surface temperatures in the central and eastern Pacific Ocean. During El Niño events, warmer ocean waters weaken the usual trade winds that blow from east to west across the Pacific. This shift alters atmospheric circulation and disrupts weather patterns around the world.

In simple terms, the Pacific Ocean acts like a giant climate engine. When its waters heat up unusually, the effects ripple across continents, triggering droughts in some regions and floods in others.

A “Super El Niño” is an exceptionally strong version of this event. These occur only occasionally but have far-reaching global consequences, including extreme heat, floods, droughts and changes in storm activity.

Why scientists are worried this time

Recent climate forecasts suggest that the world could see a strong or even super El Niño developing during 2026. Scientists have detected unusually warm waters building in the equatorial Pacific — a key signal that such an event could be forming.

Weather agencies say the current La Niña phase is weakening, increasing the likelihood of a transition toward El Niño conditions later in the year.

Historically, powerful El Niño events occur roughly every 10–15 years, and they often lead to spikes in global temperatures. Some researchers warn that the next major event could push global temperatures to record highs by 2027.

Why India could feel the heat

India is particularly sensitive to ENSO changes because they strongly influence the Indian summer monsoon, which provides about 70 per cent of the country’s annual rainfall.

During El Niño years, India often experiences:

• Higher-than-normal temperatures
• Weaker monsoon rainfall
• Greater risk of drought in some regions

Historical data shows that many major droughts in India have coincided with El Niño years, when the monsoon weakens or becomes erratic.

Climate experts say that a strong El Niño could make the coming summers hotter and drier, especially across northern and central India.

Heatwaves may intensify

Another major concern is the possibility of severe heatwaves. El Niño typically amplifies global warming signals by releasing heat stored in the ocean into the atmosphere.

This can cause prolonged heat spells across South Asia. In recent years, India has already witnessed record-breaking heat, and scientists warn that El Niño could worsen the trend.

Urban areas may be particularly vulnerable due to the urban heat island effect, where cities trap more heat because of concrete structures and reduced vegetation.

What it means for agriculture and the economy

A weaker monsoon can have serious consequences for India’s agriculture sector, which still depends heavily on rainfall.

Reduced rainfall can lead to:

• Lower crop yields
• Water shortages
• Rising food prices

Key crops such as rice, sugarcane, cotton and oilseeds may be affected if rainfall becomes insufficient or erratic.

In strong El Niño years, there is also about a 60% chance that some regions of India may experience drought conditions, according to studies on past climate patterns.

Climate change is raising the stakes

Scientists say climate change may be intensifying the impacts of El Niño events. Warmer oceans and rising global temperatures could make extreme El Niño events more frequent and more powerful in the future.

This means that even a naturally occurring climate cycle like El Niño can combine with human-driven warming to produce more severe weather.

Too early for certainty, but warning signs are clear

Experts caution that forecasting El Niño months in advance remains challenging because of what scientists call the “spring prediction barrier”, which makes seasonal predictions less reliable during this period.

However, with multiple climate models pointing toward warming in the Pacific, researchers say governments and communities should begin preparing for the possibility of extreme heat, erratic monsoon and climate disruptions.

If a super El Niño does emerge, the coming years could test India’s resilience — from water management and agriculture to disaster preparedness — as the country faces the growing reality of a changing climate.
