MANILA, Philippines – Get ready to grab your umbrellas! The rainy season has officially begun in the Philippines, with the state weather bureau PAGASA announcing its onset across the western parts of Luzon and Visayas this Monday, June 2. This declaration signals a significant shift in the country’s weather, moving away from the hot, dry months.

According to PAGASA, the consistent presence of the southwest monsoon, or habagat, over the past five days brought scattered to widespread rains to these regions. This sustained pattern of rainfall, meeting specific criteria including at least 25 millimeters of cumulative rainfall over five days (with 1 mm for three consecutive days in more than half of 13 monitoring stations) and prevailing westerly winds, officially triggered the declaration. It marks the formal start of the wet season that Filipinos are now accustomed to, coming just three days after PAGASA initially announced the start of the habagat season on Friday, May 30.

While the rains are here, PAGASA noted that “monsoon breaks” – periods with less rainfall – can still occur, potentially lasting for several days or even weeks. Historically, the rainy season typically begins in the second half of May or first half of June and continues until November.

For the period of June to November, PAGASA estimates that 11 to 19 tropical cyclones may form within or enter the Philippine Area of Responsibility. So far, there have been no tropical cyclones in 2025.

PAGASA has advised the public and all concerned agencies to take precautionary measures against the adverse impacts of the rainy season, habagat, and other climate and weather events.
