MANILA — El Niño conditions have taken hold in the tropical Pacific, Philippine weather authorities declared Tuesday, marking the official onset of a climate pattern poised to reshape weather across vast swaths of the globe through early next year.
Sea surface temperature anomalies in key monitoring regions reached the critical +0.5°C threshold in May, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). While the broader atmosphere has yet to fully couple with the warming ocean — the classic hallmark of a mature El Niño — forecasters say the transition is well underway.
Climate models point to an 82 percent probability of full El Niño development in the May-July period, climbing to over 90 percent by August. Many forecasts suggest the event could strengthen into a strong or even “very strong” (sometimes colloquially called “Super”) El Niño by late 2026, with a high likelihood of persistence through the Northern Hemisphere winter.
A Warmer, More Extreme World
El Niño events occur irregularly every two to seven years when unusually warm waters in the central and eastern equatorial Pacific alter global atmospheric circulation. The current shift comes against the backdrop of long-term human-caused warming, which scientists say amplifies the heat and extremes associated with the phenomenon.
For the Philippines, the near-term outlook is mixed. The southwest monsoon, or habagat, may initially deliver adequate or even enhanced rainfall in western parts of the archipelago through September. But drier conditions are expected to take hold later in the year, with heightened drought risk extending into early 2027.
Agriculture, water resources and energy demand are particularly vulnerable. Past strong El Niños have strained reservoirs, reduced rice yields and increased the risk of wildfires and heat-related illnesses.
Globally, a developing El Niño typically:
- Boosts the odds of record-high temperatures in 2026 or 2027.
- Brings drier conditions to Southeast Asia, Australia, Indonesia and parts of southern Africa and South America.
- Increases flood risk in parts of the United States, East Africa and the west coast of South America.
- Tends to suppress Atlantic hurricane activity while potentially altering tropical cyclone behavior in the western Pacific.
Uncertainty Remains on Peak Strength
While confidence is high that El Niño will develop and persist, the ultimate intensity is less certain. Some models hint at anomalies exceeding +3°C by year’s end — rivaling the powerful 2015-16 event — but forecasters caution that significant ocean-atmosphere coupling over the coming months will determine whether it reaches “strong” or “very strong” status.
International agencies including NOAA have maintained an El Niño Watch, with similar outlooks projecting emergence this summer and continuation through winter.
PAGASA and government agencies are urging early preparation: reviewing water management plans, bolstering drought-resistant crops, and updating disaster protocols. Officials emphasize that while El Niño brings challenges, proactive measures can limit the damage.
The announcement underscores a sobering reality: in an already warming climate, the return of El Niño is less a rare anomaly than another layer of stress on societies and ecosystems already navigating volatility.
