Earth ‘Almost Entirely in the Red’: Intensifying Super El Nino Smashes Ocean Heat Records

Super El Niño is continuing to intensify, scientists have warned, with new forecasts suggesting the climate phenomenon could maintain its grip on global weather well into next year. Experts say the event is now pushing into unprecedented territory, with vast swathes of the planet forecast to experience unusually warm conditions as the Pacific Ocean releases enormous amounts of stored heat.

The latest update from the World Meteorological Organization (WMO) predicts that El Niño will continue strengthening ahead of a forecasted peak in December, Daily Mail reported. Scientists say the powerful climate pattern is likely to influence temperatures and rainfall across much of the world in the coming months. Super El Nino Projected To Cause Over 4,50,000 Deaths Across Globe in Next 6 Months: Report.

Global Temperatures Approach Historic Highs

The warning comes as meteorologists share striking maps showing large areas of the globe shaded red, indicating a heightened likelihood of above-average temperatures. US meteorologist Ryan Maue described the outlook in a post on X, writing: ‘New maps show Earth almost entirely in the red.

‘El Niño continues at 'maximum power' into the winter with planetary heating dialled up everywhere except the United States.’ According to the WMO, there is a near-100 per cent chance that El Niño will persist through February 2027. The agency says the event could rank among the strongest observed since at least 1950. El Nino Triggers Dual Health Crisis in India As WHO Issues High-Risk Alert Over Dengue, Malaria Surge.

Record Ocean Heat Drives Rapid Strengthening

WMO Secretary-General Celeste Saulo said: ‘El Niño is firmly established and strengthening rapidly.’ She explained that El Niño does not create new heat but instead releases heat that has accumulated beneath the ocean surface. ‘The ocean it's drawing from is the warmest we've ever measured it,’ Professor Saulo said. ‘There is simply more heat available to release.’

The widely used Niño 3.4 index rose from 1.6°C above normal in June to 2.5°C above normal in August, highlighting the rapid strengthening of the event. WMO forecasts suggest the October-to-December average anomaly could reach about 3.7°C, with conditions peaking around December.

Climate scientist Zeke Hausfather said: ‘This year's El Niño continues its climb into uncharted waters. ‘Niño 3.4 region anomalies are now at 3.4°C above normal, higher than any prior El Niño event on record.' Climate and energy researcher Leon Simons joked that forecasters are witnessing a ‘super-duper El Niño’, adding: ‘We're going to need a bigger y-axis.’

The update also points to an overwhelming likelihood of above-average sea surface temperatures across large parts of the globe during the final months of 2026. Scientists warn that the combination of a powerful El Niño and exceptionally warm oceans could increase the risk of heat extremes, floods and droughts in different regions of the world for months to come.

Global Rainfall Patterns and Regional Climate Shifts

Figures show that while sea surface temperatures are expected to start to slowly decrease in early 2027, El Niño will persist well into March. While each El Niño varies, the event typically brings increased rainfall in parts of southern South America, the southern United States, parts of the Horn of Africa and central Asia.

In contrast, there will be drier conditions over Central America, northern South America, the Caribbean, Australia, Indonesia, and parts of southern Asia.

The strongest heat signals are forecast across southern and western North America, Central America, the Caribbean, Europe, North Africa, and much of Asia. In the Southern Hemisphere, Northern South America is likely to see the strongest warming, while Southern Africa is forecast to experience widespread above-normal temperatures.

In Australia, warmer conditions are mainly expected along the western, southern, and eastern coasts, with no clear trend in the north. Tropical regions are also forecast to be hotter than normal, especially Equatorial Africa and parts of Southeast Asia and the Maritime Continent.

Mechanism Behind the Southern Oscillation Cycle

El Niño is part of a naturally occurring weather cycle called the El Niño Southern Oscillation that changes between a hot and cool phase once every two to seven years.

During the hot, El Niño part of the cycle, the trade winds that normally blow warm water from the Pacific towards Australia slow or even reverse. This allows warm water to collect near the surface of the equatorial Pacific Ocean off the west coast of South America, driving up global average temperatures. Scientists have warned that this year's 'Super El Niño' has already smashed historical temperature records, months before reaching its peak.

Stormy Autumn and Winter Outlook for the United Kingdom

Brits have been told to prepare for a stormy autumn thanks to the weather phenomenon. According to scientists, Brits should prepare for 'heavy rainfall and flooding' from as early as October.

'A strong El Niño is likely to increase the chances of wetter, stormier conditions for the UK from October to December,' said Dr Amulya Chevuturi, senior hydroclimate scientist, UK Centre for Ecology & Hydrology. 'The North West is expected to be worse affected than the South East.'

A bit of rain might sound quite appealing following the months of relentless heat. However, Professor Bill McGuire, Professor Emeritus of Geophysical Hazards, warns that the stormy autumn will likely be followed by a bitterly cold winter. 'Powerful El Niños typically bring mild, stormy Autumns and early Winters to the UK, followed by bitter cold, although this isn't set in stone,' he said.
