PRESS RELEASE
DOST-PAGASA S&T Media Service
Quezon City, 30 May 2026

START OF THE SOUTHWEST MONSOON

Ahead of the possible onset of the rainy season, the DOST-PAGASA officially announces the start of the Southwest Monsoon or Habagat over the Philippines, which is one of the precursors of the onset of the rainy season.

As Habagat becomes the dominant weather system, occasional to frequent rains and thunderstorms are expected, particularly over the western sections of the country. These conditions may signal the possible onset of the rainy season in the coming days.

However, there may be rain breaks that last a few days or weeks, known as monsoon breaks.
