Quezon City , 30 May 2025
Recent weather analysis over the past several days has shown the persistence of low-level southwesterly winds over the western section of Luzon and the Frontal System over Extreme Northern Luzon . With the weakening of the Easterlies, these developments indicate the beginning of the Southwest Monsoon (Habagat) in the Philippines – one of the precursors of the onset of the rainy season.
As the Habagat becomes more dominant, occasional to frequent rains and thunderstorms are expected particularly over the western sections of the country. This may lead to the possible onset of the rainy season within the next two (2) weeks. Periods of the monsoon breaks may also occur.
PAGASA will continue to monitor the weather situation of the country. The public and all concerned agencies are advised to take precautionary measures against the adverse impacts of the Habagat such as floods and rain-induced landslides. For more information, you may contact the Weather Forecasting Section, Weather Division at telephone number 8284-0800 local 4801.
