Record-Intensity El Niño Forecasted to Persist Through February 2027

This record-breaking El Niño event is expected to exacerbate existing climate challenges, affecting economies and livelihoods worldwide.

• El Niño conditions emerged in June 2026, with sea surface temperatures rising rapidly, indicating a potential record-breaking event.
• The World Meteorological Organization forecasts a nearly 100% chance of this El Niño persisting through February 2027, leading to extreme global weather.
• Early impacts include record heat in the U.S., water rationing in Puerto Rico, and disruptions to fisheries in the eastern Pacific.

• Historical precedents: Previous strong El Niño events, like those in 1997-98 and 2015-16, caused significant global disruptions, setting a concerning precedent for the current situation.
• Climate change interaction: This El Niño is compounded by anthropogenic climate change, with rising sea temperatures intensifying its effects.
• Global implications: The event is expected to push global temperatures higher, potentially making 2026 and 2027 the hottest years on record.

The 2026 El Niño is shaping up to be a climate phenomenon of unprecedented scale, driven by a combination of natural oceanic cycles and human-induced climate change. Since June 2026, scientists have observed rapid increases in sea surface temperatures in the eastern tropical Pacific Ocean, with anomalies projected to exceed 2.5–3.6°C in the Niño 3.4 region. This marks a significant escalation compared to previous events, which were already known for their disruptive impacts.

The World Meteorological Organization (WMO) has issued its most definitive forecast yet, indicating a nearly 100% likelihood that this El Niño will persist through February 2027. This forecast is alarming, as it suggests that the extreme weather patterns associated with El Niño—such as droughts, floods, and heatwaves—will not only continue but intensify. The early impacts have already been felt globally, with the hottest summer on record in the U.S., severe drought conditions in Sudan exacerbating hunger crises, and water rationing measures being implemented in Puerto Rico.

The interaction between this El Niño and ongoing climate change is particularly concerning. As greenhouse gas emissions continue to warm the planet, the baseline temperatures are rising, creating a feedback loop that amplifies the effects of El Niño. UN Secretary-General António Guterres has highlighted that we are witnessing the "supersizing" of El Niño, as rising sea temperatures and accumulated subsurface heat in the western Pacific interact with long-term global warming trends.

The implications of this event are far-reaching. The UN Food and Agriculture Organization and the World Food Programme have already issued appeals for donations to avert a global humanitarian crisis, as agricultural disruptions and higher food prices loom. The Panama Canal Authority has reduced daily transits due to low water levels, signaling the potential for significant disruptions in global trade. As governments in regions like California and Southeast Asia prepare for increased flooding, droughts, and wildfires, the economic and social ramifications of this El Niño will be felt across multiple sectors.

• Farmers: Facing potential crop failures and increased food prices due to disrupted weather patterns.
• Energy sectors: Anticipating spikes in demand and potential supply chain disruptions.
• Coastal communities: Experiencing heightened risks from flooding and erosion.
• Governments: Needing to allocate resources for disaster preparedness and response.

• Temperature trends: Monitor global temperature records to see if 2026 and 2027 become the hottest years on record, which would indicate the severity of this El Niño.
• Agricultural reports: Keep an eye on crop yield forecasts and food price trends, as these will reflect the immediate economic impacts of the El Niño.
• Disaster preparedness initiatives: Watch for government responses in vulnerable regions, including funding for infrastructure improvements and emergency services.
