The 2026 El Nino is pushing Pacific temperatures above past super event benchmarks for June. Scientists say it is developing over unusually warm global oceans, which could change or intensify its effects.

The developing El Nino of 2026 is showing signs of becoming one of the most unusual and potentially powerful climate events ever observed, with ocean temperatures in the key Pacific monitoring region already running ahead of previous super El Nino years such as 2015, 1997 and 1982.
New sea-surface temperature data from the Nino 3.4 region, the central Pacific Ocean area used to monitor El Nino development, shows that temperatures have reached unprecedented levels for this time of year.
By June 17, temperatures were more than 0.58 degrees Celsius above the previous daily record and had set 19 consecutive daily record highs.
The latest chart tracking Nio 3.4 sea-surface temperatures since 1982 reveals that the 2026 curve has surged well above the historical average and is tracking higher than the corresponding periods in the lead-up to the powerful El Nino events of 1982, 1997 and 2015.
Climate scientists describe El Nino as a periodic warming of the central and eastern tropical Pacific Ocean that alters global weather patterns. Strong El Nino events are often linked to droughts, floods, marine heatwaves, coral bleaching and shifts in storm tracks across the world.
What makes 2026 particularly concerning is that the event is unfolding in oceans that are already significantly warmer due to long-term global warming.
A comparison of global sea-surface temperature anomaly maps from June of 1982, 1997, 2015 and 2026 highlights a dramatic difference.
While earlier super El Nino years developed in a climate system with large areas of near-normal ocean temperatures, the 2026 map is dominated by widespread red shades, indicating unusually warm waters across much of the Pacific, Atlantic and Indian Oceans.
The tropical Pacific warming associated with El Nino is therefore being superimposed on an already overheated global ocean.
This means the atmosphere may not respond in exactly the same way it did during previous super El Nino events. Historically, El Nino strengthens the transfer of heat from the ocean to the atmosphere, often helping push global temperatures to new highs.
However, with oceans now carrying substantially more background heat than during past events, the impacts could be amplified or altered.
Meteorologists are closely monitoring whether the event evolves into a full-fledged Godzilla El Nino similar to those seen in 1982-83, 1997-98 and 2015-16. Those episodes triggered severe droughts in parts of Asia and Australia, devastating floods in South America, and widespread ecological damage across the tropics.
For India, the timing is particularly significant as the southwest monsoon is already struggling. While a strong El Nino typically weakens monsoon circulation, experts caution that the relationship is no longer as straightforward as it once was because warmer oceans around the globe are increasingly influencing regional weather patterns.
With record-breaking Pacific temperatures continuing to rise in June, climate scientists say the coming months could provide the clearest indication yet of how El Nino behaves in a world that is already hotter than ever before.
