2026-2027 El Niño phenomenon intensification

Overview

The 2026-2027 El Niño phenomenon is intensifying, with sea surface temperature anomalies in the Niño 3.4 region approaching the “very strong” threshold of +2°C. In the Niño 1+2 region near Peru, anomalies have hit 3.3°C. This warming has led to a decline in chlorophyll-a concentrations in the central equatorial Pacific, threatening marine food webs. Scientists warn that the interaction between natural cycles and anthropogenic warming makes the global impact increasingly unpredictable, with the event potentially lasting until autumn 2027.

Meteorological agencies report significant intensification. NOAA has raised the probability of a “very strong” event to 95% for the October-December 2026 period, with a median sea surface temperature anomaly forecast at +2.66°C. There is a 97% chance the phenomenon will persist until the spring of 2027. Some projections suggest a 69% chance that this could become the most intense event recorded since 1950.

Environmental risks are escalating. An analysis by Amazon Conservation highlights a historical correlation between strong El Niño events and subsequent wildfire crises, noting that the 2023 event preceded record forest losses in 2024. Researchers warn the upcoming cycle could trigger similar or more severe primary forest losses in the Amazon basin.

Regional concerns persist across South America. In Peru, the ENFEN commission has warned of a potential “extraordinary” El Niño Costero. In Brazil, authorities report intense rainfall and extreme winds in the south and southeast, while the Amazon and northeast face drought. In Bolivia, the climate crisis has already caused a 20% drop in milk production in the La Paz department. In Europe, concerns remain regarding temperature increases and persistent weather patterns.
