The United Nations predicts a strong 80% chance of El Niño between June and August, warning that the world is entering a high-probability phase of the warming climate phenomenon that could significantly alter global weather patterns in the coming months. The World Meteorological Organization (WMO) said there is an 80% chance of El Niño Between June-August, driven by unusually warm ocean conditions in the tropical Pacific.

Based in Geneva, the WMO cautioned that El Niño conditions are already developing and are expected to influence temperature, rainfall, and extreme weather events across multiple regions.

What the WMO Forecast Says

According to the WMO’s latest climate update, ocean and atmospheric indicators are rapidly shifting toward El Niño conditions.

Key observations include:

• 80% probability of El Niño developing between June and August
• Nearly 90% likelihood of El Niño forming by November
• Conditions expected to be moderate to potentially strong
• Sea-surface temperatures in the Pacific are already approaching El Niño thresholds

The WMO confirmed that sub-surface ocean temperatures in the Equatorial Pacific are currently more than 6°C above average, a strong signal of developing warming conditions.

What Is El Niño and Why Does It Matter

El Niño is a natural climate cycle that occurs every two to seven years, typically lasting 9 to 12 months. It is marked by warming of surface waters in the central and eastern Pacific Ocean, which disrupts global wind and rainfall patterns.

Scientists say the 80% chance of El Niño between June-August is significant because even moderate events can trigger major climate disruptions worldwide.

• Alters the global rainfall distribution
• Increases the likelihood of droughts and floods
• Intensifies heatwaves across land and ocean
• Influences storm and cyclone formation patterns

Global Weather Impacts Expected

The WMO warned that El Niño will likely increase the frequency of extreme weather events across multiple regions.

Expected impacts include:

• Above-normal global temperatures across most regions
• Higher risk of heatwaves on land and in oceans
• Increased likelihood of heavy rainfall and flooding events
• Worsening drought conditions in vulnerable regions

Regional forecasts also suggest:

• Below-normal rainfall in the Greater Horn of Africa
• Weak monsoon rainfall across parts of South Asia
• Warmer and drier conditions in Central America

These patterns reinforce concerns linked to the 80% chance of El Niño between June and August, especially for agriculture and water systems.

Ocean and Storm System Effects

El Niño also affects tropical storm activity. The WMO noted that warmer Pacific waters can significantly alter hurricane formation patterns.

• Increased hurricane activity in the central and eastern Pacific
• Reduced cyclone formation in the Atlantic Ocean
• Enhanced ocean heat content is fueling extreme weather systems

The organization stressed that a warming baseline climate is amplifying the impacts of El Niño events.

Climate Change and Intensifying Impacts

While El Niño itself is a natural cycle, the WMO clarified that climate change does not necessarily increase its frequency. However, it does intensify its impacts.

• Warmer oceans provide more energy for storms
• Higher atmospheric moisture increases rainfall extremes
• Heatwaves become more severe during El Niño years

UN Secretary-General António Guterres warned that “El Niño is arriving on our doorstep,” calling it an urgent climate signal requiring immediate global action.

Final Outlook

With an 80% chance of El Niño between June and August, the world is entering a period of heightened climate volatility. The WMO warns that even a moderate El Niño could significantly amplify heatwaves, rainfall extremes, and drought risks across continents.

As conditions continue to develop, global preparedness and climate adaptation measures will be crucial to managing the widespread impacts expected in the months ahead.
