According to the National Oceanic and Atmospheric Administration, the current La Niña weather pattern is expected to transition to a potentially record-breaking El Niño event later this year. Experts warn this 'super El Niño' could be one of the strongest on record, with impacts potentially felt worldwide.

Why it matters

El Niño weather patterns can have far-reaching effects, from droughts and wildfires to flooding and extreme storms. A 'super El Niño' of the magnitude being forecast could disrupt global weather patterns and lead to significant environmental and economic consequences in many regions.

The details

NOAA's latest forecast indicates the current La Niña will give way to an ENSO-neutral period in the next month, before a strong El Niño emerges by mid to late summer. For an El Niño to be considered 'super,' ocean temperatures must exceed 2 degrees Celsius above normal - a threshold last reached over a decade ago in 2015, and before that in 1998 and 1982. Experts say the combination of current cyclone activity suggests this upcoming El Niño could be one of the most extreme on record.

  • The current La Niña is expected to transition to ENSO-neutral conditions within the next month.
  • El Niño is forecast to emerge by mid to late summer 2026.
  • The last 'super El Niño' events occurred in 2015, 1998, and 1982.

What they’re saying

“So once those sea surface temperatures become a half a degree above normal, it becomes an El Niño. but when it exceeds two degrees above normal – and these are degrees centigrade – so when it goes to two degrees centigrade above normal, then we go into a super El Niño conditions.”

What’s next

NOAA will continue to monitor the development of the El Niño pattern in the coming months and provide updated forecasts on its potential strength and impacts.

The takeaway

The prospect of a 'super El Niño' event, potentially the strongest in over a century, underscores the need for communities to prepare for the possibility of severe weather disruptions and environmental challenges in the year ahead.
