PAGASA declares end of Southwest Monsoon season

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has officially declared the end of the Southwest Monsoon, locally known as Habagat, on Tuesday, October 7, 2025.

This declaration signifies the conclusion of the rainy season for the western parts of Luzon and Visayas.

PAGASA observed a weakening of the southwest monsoon over the past weeks, attributed to the strengthening of high-pressure systems in East Asia and the southward shift of the Intertropical Convergence Zone.

The country is now entering a transitional period towards the Northeast Monsoon, or Amihan season, which is expected to commence in the upcoming weeks.

Historically, the Amihan season typically begins in late October, although the onset has varied in recent years.

The Amihan season is characterized by cooler temperatures, with the peak usually occurring in January and February, bringing significant temperature drops in the Cordilleras and Metro Manila.
