The National Oceanic and Atmospheric Administration (NOAA) warns of a developing "Super" El Niño that could be the strongest in 150 years [4].

This event threatens to disrupt global agriculture and weather patterns, potentially causing extreme floods and droughts that could destabilize food security for several years.

NOAA issued an advisory on June 11, 2026, stating there is an 81% chance [1] that the El Niño will become a very strong event. Climatologists define a Super El Niño by sea-surface temperatures in the equatorial Pacific that rise more than two degrees Celsius above normal [3]. This temperature anomaly is a result of the El Niño-Southern Oscillation, a pattern that scientists said is being amplified by ongoing climate change.

The event is expected to peak during the 2026-2027 winter season. Experts said it is one of the most destructive climate events in more than a century [5]. The resulting weather shifts are expected to trigger worldwide impacts, including severe downpours in some regions and intense droughts in others.

Beyond the immediate weather risks, the phenomenon poses a significant economic threat. The disruption of crop yields is expected to create a global supply shock. This instability could keep global food prices elevated until 2028 [2].

Scientists said the warming of the equatorial Pacific Ocean acts as a catalyst for these global shifts. The interaction between the ocean and atmosphere redistributes heat and moisture, which alters jet streams and precipitation patterns across the globe.

“NOAA rates an 81% chance of the El Niño becoming a very strong event.”

The convergence of a Super El Niño with long-term climate change creates a compounding effect that increases the volatility of global weather. Because the event impacts the primary agricultural belts of the world, the risk is not merely meteorological but systemic, threatening the stability of the global food supply chain for the next two years.
