The El Niño climate phenomenon, linked to record global temperatures, is now locked in place in the Pacific Ocean and could develop into the strongest on record, according to Australia’s Bureau of Meteorology. Climatologists are watching the strengthening El Niño with increasing alarm, saying the forecasts from climate models in the coming months are “mind blowing” and “astounding.” Globally, experts have said a strong El Niño could work in tandem with global heating to deliver the hottest year on record either this year or, more likely, in 2027.
What Makes This El Niño Different?
The bureau has stressed that the strength of an El Niño does not necessarily correlate with the strength of impacts in Australia, but the system generally brings hotter and drier conditions in winter and spring for southern and eastern parts. The climate phenomenon is characterised by warming sea surface temperatures in the central and eastern tropical Pacific Ocean, with the subsequent atmospheric upset fuelling more severe storms in some parts of the world and hot, dry conditions in others.

Key Indicators of El Niño Strength
A major indicator of the strength of an El Niño is the sea surface temperatures in one area of the equatorial Pacific – known as Niño 3.4. Dr Zhi-Weng Chua, a senior climatologist at the bureau, said the highest reliable temperature value for previous El Niños was a monthly average of +2.6°C seen in that Pacific region in January 1983. But he said climate models were suggesting this El Niño could peak between +2.2°C and above +3°C. “There is a realistic chance that the peak anomaly of this event will rank in the top events, with a chance it could rank as the highest. It is remarkable, and it shows just how much heat there is in the ocean. It’s perhaps not a surprise, given climate change and how oceans have been gathering heat in the last few decades.”
Comparison of Past El Niño Events
| Year | Peak Niño 3.4 Anomaly (°C) | Global Temperature Impact |
|---|---|---|
| 1982-1983 | +2.6 | Record global warming |
| 1997-1998 | +2.4 | Extreme weather worldwide |
| 2015-2016 | +2.3 | Hottest year at that time |
| 2023-2024 (projected) | +2.2 to +3.3 | Potential hottest on record |
Key Takeaways for Preparedness
- Monitor local forecasts for heatwaves and drought conditions.
- Prepare for extreme weather including storms and flooding in some regions.
- Stay informed with updates from the Bureau of Meteorology.
- Stock up on essentials like water, food, and emergency supplies.
FAQ
What is El Niño?
El Niño is a climate pattern characterized by warming sea surface temperatures in the central and eastern tropical Pacific Ocean, which disrupts global weather patterns.
How strong could this El Niño become?
Climate models suggest this El Niño could peak with a Niño 3.4 anomaly between +2.2°C and above +3°C, potentially making it the strongest on record.
What are the expected impacts of a strong El Niño?
Impacts include hotter and drier conditions in parts of Australia, more severe storms in other regions, and a likely contribution to record global temperatures.
