La Nina Watch: PAGASA Warns Of Possible Wetter Months Ahead

The Department of Science and Technology–Philippine Atmospheric, Geophysical and Astronomical Services Administration (DOST-PAGASA) has raised a La Niña Watch as signs point to a potential shift in weather patterns in the coming months.
PAGASA reports that the El Niño–Southern Oscillation (ENSO) in the tropical Pacific remains in a neutral phase for now and is expected to persist through the August-September-October 2025 season. However, climate models suggest a growing likelihood—starting as early as September—of a short-lived La Niña developing and continuing through the October-November-December period.
What is La Niña and why does it matter?
La Niña, the cool phase of ENSO, happens when sea surface temperatures in the central and eastern equatorial Pacific become unusually cooler than average. When forecasts show a 55% or higher probability of La Niña forming within the next six months, PAGASA issues a La Niña Watch to alert the public and concerned agencies.
Historically, La Niña brings wetter conditions to the Philippines. This often means above-normal rainfall and an increased number of tropical cyclones toward the latter part of the year. While rain is essential, excessive precipitation can lead to floods and landslides, especially in vulnerable areas.
Stay alert, stay safe
PAGASA emphasizes that they will continue to monitor the situation closely and provide timely updates. The agency urges local governments, disaster response units, and the general public to stay informed and prepare for possible impacts.
For now, the outlook is not yet certain, but with the probability rising, it pays to be ready for the possibility of wetter and stormier months ahead.
