The latest update on the ‘super El Niño’ development in the Pacific Ocean has revealed it could start impacting the world sooner than it was thought.
The El Niño, which was previously predicted to have it developed next year, has since had the full force of its consequences reeled in a little closer than expected.
While initially, it was believed this would create the hottest summer in 2027 as Pacific waters heat up more than what’s average for the time of year, causing droughts, October 2026 to February 2027, has been the new forecast from the National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center.
This means the severe weather predictions could be hitting certain parts of the world a lot faster than what was thought before.

A new ENSO forecast published 14 May, shows that the NOAA estimates a 65 per cent chance that the El Niño will be ‘strong’ or ‘very strong’ starting in October, which could be the strongest in history.
Currently, the strongest El Niño occurred from 1997 to1998.
According to The Guardian, it led to the deaths of 23,000 people and cause between £21 billion to £28 billion in damage due to the droughts, cyclones, wildfires and floods.
There is also an 82 per cent chance that El Niño will arrive between now and July, per the NOAA, which is around a 20 percentage-point increase from NOAA’s April forecast.

The Met Office has since spoken about the El Niño, warning it could cause ‘some of the most impactful episodes in recent decades’.
“Other organisations around the world have other definitions and thresholds for what constitutes El Niño conditions, but this will be such a significant event, if it happens, that it will be above all of those thresholds and there will be no doubt that we’re in an El Niño,” said Grahame Madge, climate science communicator at the Met Office.”
He added: “A ‘super’ El Niño is not a term we subscribe to, but it does underpin the fact that this is likely to be a significant event.
“Scientists are telling us that this could be the strongest El Niño event so far this century, comparable to the notable El Niño event in 1998.”
How does an El Niño year happen?
Strap in, folks. It’s time for some science.
It all starts with something called trade winds, which are permanent winds around the equator, which usually blow from east to west. So in the equatorial Pacific, they blow from the Americas towards Australia and New Zealand.
As the wind blows the water east, it is warmed by the sun, so by the time it gets to the other side of the Pacific, the warm water causes hot air to rise, leading to warm, wet and unsettled weather. Meanwhile, colder water from deeper in the ocean rises in the east to replace the water blown west.

But during El Niño years, this gets disrupted.
Trade winds are weakened or even reversed, the temperature difference between the east and west is cancelled out, and usually cold parts of the ocean warm up.

Rainfall and wind patterns change across the equatorial Pacific, which has a knock-on effect around the world.
