El Niño conditions confirmed in the Pacific Ocean
Scientists in the United States have confirmed that El Niño has officially started in the tropical Pacific. The system is known for warming ocean waters and influencing weather patterns around the world.
The National Oceanic and Atmospheric Administration reported that sea surface temperatures in key areas of the Pacific have risen above 0.5°C compared to normal levels. This is the threshold used to define the start of an El Niño event.
Experts also noted that wind patterns above the equatorial Pacific are changing. This shows that the atmosphere is now reacting to the warming ocean.
What makes this El Niño unusual
Forecast models suggest this event could grow into a very strong or even “super” El Niño. Some simulations show Pacific ocean temperatures rising more than 3°C above average later this year.
A strong El Niño is defined when sea temperatures rise more than 1.5°C above normal. A very strong event goes beyond 2°C.
The World Meteorological Organization says confidence is increasing that this could become one of the most powerful events on record.
Possible impact on global weather
El Niño often increases global temperatures, especially when combined with long term climate warming.
If this event strengthens further, it could:
• Push global temperatures toward new records
• Increase flood risk in parts of South America
• Raise drought risk in Australia and parts of Asia
• Disrupt rainfall patterns across South Asia, including monsoon changes
• Increase heatwaves and extreme weather events in many regions
Weather experts also warn that effects can last well beyond the peak phase.
Why 2027 could be a key year
Some forecasts suggest the strongest impact may be felt in 2027. That is when ocean and atmospheric effects can combine with long term warming trends.
Scientists say past major El Niño events, such as in 1982–83, 1997–98, and 2015–16, led to major global climate disruptions.
How strong could it get
Current models show a 63% chance of a very strong El Niño during the November to January period.
However, scientists also caution that forecasts are not certain. Ocean and wind patterns can still change over the coming months.
