The WMO warns that El Niño could become the strongest in four decades, bringing extreme heat, floods and droughts worldwide through 2027
GENEVA: The World Meteorological Organization (WMO) has warned that the current El Niño could become the strongest in four decades, increasing the risk of extreme weather across the world.
In its latest forecast released on October 21, the UN weather agency said Pacific Ocean temperatures could rise 3.8°C above average between November 2026 and January 2027.
The phenomenon is expected to peak in December, with its effects continuing well into 2027.
WMO Secretary-General Celeste Saulo warned that the developing El Niño could exceed the monitoring scale used for the past 40 years.
Floods, droughts and extreme heat expected
El Niño occurs when unusually warm waters develop across the central and eastern Pacific Ocean. These changes disrupt global atmospheric circulation, influencing rainfall, temperatures and storms.
The WMO identified several regions facing increased risks.
East Africa could experience heavier rainfall and flooding. Southern Africa faces greater drought risks, threatening agriculture and water supplies.
Southeast Asia could see higher temperatures and reduced rainfall, increasing pressure on farming and water resources.
Parts of the Americas may also experience unusual rainfall, while other areas face worsening drought conditions.
UN calls for urgent preparedness
The WMO has urged governments and humanitarian organisations to strengthen early-warning systems and prepare vulnerable communities.
Officials warned that extreme weather could affect food security, public health, agriculture and access to clean water.
Climate change could further intensify the impacts of El Niño, particularly during prolonged periods of extreme heat.
Impact to expect
Countries could face greater pressure on food production, water supplies and emergency services.
For the UAE, any effects will depend on regional weather patterns and forecasts from the National Centre of Meteorology.
The WMO stressed that early preparation can reduce damage and protect communities as the event strengthens.
