El Niño Could Become Strongest on Record, UN Weather Agency Warns

The current El Niño weather pattern is on track to intensify and could become the strongest ever recorded, the World Meteorological Organization (WMO) warned on Thursday. The UN agency stated with near-total certainty that the event will persist into early 2027, raising significant risks for global weather patterns, agricultural markets, and supply chains.

A 'Supersized' Phenomenon

The WMO's latest forecast indicates a near 100% likelihood that El Niño will continue through February 2027, a degree of certainty the agency said it has never before expressed for this phenomenon. The event is being fueled by exceptionally warm Pacific Ocean temperatures, which are already more than 2 degrees Celsius (3.6 degrees Fahrenheit) above normal.

"If this trajectory continues, it may be stronger than anything since our monitoring began. So literally off the charts," WMO Secretary-General Celeste Saulo said at a Geneva press conference. This places the current event in the top "very strong" category in records dating back to 1950.

Market and Economic Implications

A powerful El Niño can drastically alter global weather, increasing the frequency of destructive events like droughts, floods, and typhoons. These disruptions pose a direct threat to the global economy, particularly the agricultural and energy sectors.

The WMO noted the event has already impacted soft commodities in tropical areas, contributing to a severe food crisis in Central America’s Dry Corridor. Investors are closely watching for potential volatility in agricultural futures, shipping route disruptions, and increased stress on insurance and infrastructure as the phenomenon is expected to peak toward the end of this year.

A 'Pulse' in Global Temperatures

While El Niño is a naturally occurring climate pattern, scientists note its effects are being amplified by warmer oceans. UN Secretary-General Antonio Guterres stated that "El Niño is being supersized before our eyes."

The WMO projects that the full impact on global temperatures will be felt in 2027, after the event has peaked. "Normally after an El Niño event we tend to see a pulse in the global temperatures," said Wilfran Moufouma Okia, the WMO’s chief of climate prediction services. This lagging effect means 2027 has the potential to become the warmest year on record, underscoring long-term climate risks.
