🎯 The Main Takeaway

A potential “Godzilla” or super El Niño is forecast to develop in the second half of 2026, threatening Southeast Asia with prolonged drought, extreme heat, and heightened wildfire risk.

While the term “Godzilla” is informal, scientists use it to describe an exceptionally strong El Niño event where sea surface temperatures in the equatorial Pacific rise at least 2°C above average.

The National Oceanic and Atmospheric Administration (NOAA) estimates a 62% chance of El Niño emerging between June and August 2026, with roughly a one-in-three chance it could become strong by October-December.

”The most recent El Niño, in 2023-24, was one of the five strongest on record, and it played a role in the record global temperatures we saw in 2024.”
— Celeste Saulo, Secretary-General of the World Meteorological Organization (WMO)

📡 Why It’s on Our Radar

For Southeast Asia, El Niño is not a distant climate curiosity—it is a direct threat to food security, water supply, and public health.

The region is already experiencing above-normal temperatures between March and May 2026, according to the ASEAN Specialized Meteorological Center (ASMC).

In Malaysia, temperatures have soared above 37°C in Perlis, Perak, and Kedah, while Jakarta reached 35.6°C during the recent Hari Raya holiday week.

The potential return of a super El Niño—comparable to the devastating events of 1997-98 and 2015-16—could push these impacts into crisis territory.

⚠️ What’s at Stake

Water Scarcity (🔴 High threat)

• Reduced reservoir levels across the region

• Potential water rationing in cities and rural areas

• Stress on agriculture and hydropower generation

Agriculture (🔴 High threat)

• Lower yields for rice, sugar, and palm oil—staple crops across Southeast Asia

• Rising food prices as supply tightens

• Reduced farm incomes, particularly for smallholder farmers

Wildfires (🟠 Moderate-High threat)

• Increased hotspots already detected in Indonesia (1,601 as of early April 2026)

• Transboundary haze affecting Malaysia, Singapore, and Thailand

• Elevated PM2.5 pollution causes respiratory illnesses

Public Health (🟠 Moderate-High threat)

• Heatstroke, dehydration, and heat exhaustion

• Respiratory illnesses from wildfire haze

• Increased dengue fever risk as warmer temperatures create breeding grounds for mosquitoes

Energy (🟡 Moderate threat)

• Higher electricity demand for cooling (air-conditioning, fans)

• Reduced hydropower generation as water levels drop

• Increased strain on power grids during peak hours

🌍 El Niño vs. La Niña: Understanding the Difference

Many people confuse El Niño and La Niña, but they are opposite phases of the same climate pattern—the El Niño-Southern Oscillation (ENSO) . Here is a simple breakdown:

Simple memory trick: Think of El Niño as "the little boy" (Spanish) who brings hot temperatures and dry conditions. La Niña is "the little girl" who brings cool tears (rain).

• Drought risk unknown but potentially severe

• Political instability complicates disaster response

🇵🇭 Philippines

• La Niña ending; dry season onset expected March-April

• Fewer tropical cyclones expected, but those that form may be stronger (typhoon or super typhoon category)

• Heat index values are high; potential for 40°C daytime temperatures in Cagayan Valley

• PAGASA warns of rising nighttime temperatures (trend increasing faster than daytime highs)

🇸🇬 Singapore

• La Niña fading; warmer weather expected from July 2026

• Potential 40-80% rainfall reduction in some months (based on past strong El Niños)

• Haze risk from Indonesian fires

• National heatwave response plan activated with islandwide cooling centers

• MSS forecasts El Niño possible from July 2026

🇹🇭 Thailand

• Entering the “mid-phase” of El Niño, it could shift to full El Niño by May 2026

• Water shortages expected across multiple regions

• Agricultural stress on rice, sugar, and palm oil

• Elevated PM2.5 and heatwave risks

• Southern and lower eastern regions face the highest heatwave risk

🇻🇳 Vietnam

• ENSO-neutral shifting to the warm phase by late 2026

• Earlier, longer, and more intense heatwaves are expected

• Saltwater intrusion in the Mekong Delta during the dry season

• Below-average rainfall in southern regions in the final months of 2026

• Fewer storms, but those that form may have complex, rapidly changing tracks

🔬 The Science Behind “Godzilla” El Niño

The term “Godzilla” El Niño was first popularised by NASA scientist Bill Patzert in 2015 to describe an exceptionally strong event.

It is not an official scientific term, but has been revived by Indonesia’s National Research and Innovation Agency (BRIN) to warn of a potential combination of strong El Niño and positive Indian Ocean Dipole (IOD) between April and October 2026.

Key scientific drivers:

• Unusually powerful westerly wind bursts are pushing warm water rapidly into the eastern Pacific

• Accumulated subsurface heat from the recent La Niña period is ready to be released

• Climate change is raising the baseline, making each El Niño potentially more impactful than previous ones

🏠 Why This Hits Home

For ordinary citizens across Southeast Asia, a super El Niño would mean:

• 💸 Higher food prices as crops fail and supply chains tighten

• 🚰 Water rationing in cities and villages alike

• 😓 Health risks from heatstroke, dehydration, and worsening air pollution

• 📉 Lost income for farmers, delivery riders, outdoor workers, and tourism staff

🔮 The Bottom Line

The potential return of a super or “Godzilla” El Niño in late 2026 poses a severe and multifaceted threat to Southeast Asia.

While forecasts still carry uncertainty due to the “spring predictability barrier” —when model accuracy is historically lower—the direction of travel is clear: hotter, drier, and more volatile conditions are coming.

Governments are preparing, but individuals must act as well.

Conserve water, avoid peak heat hours, wear masks when air quality deteriorates, and support vulnerable neighbors.

The question is no longer whether El Niño will return, but how strong it will be—and how ready Southeast Asia truly is.
