Habagat to bring another rainy week across the Philippines

Filipinos may want to keep their umbrellas within reach this week as the southwest monsoon, or habagat, continues to bring rain to different parts of the country.

According to PAGASA, the southwest monsoon is affecting Luzon and the western section of the Visayas, with rain showers and thunderstorms expected in several areas. 

As of 2 p.m. on Monday, Aug. 10, Metro Manila as well as other areas of Luzon were under orange and yellow rainfall warnings. A yellow rainfall warning means flooding may occur in low-lying areas, while an orange rainfall warning indicates a greater risk of flooding and possible landslides.

Zambales and Bataan may see occasional rains on Tuesday, Aug. 11, while Metro Manila, the Ilocos Region, the Cordillera Administrative Region (CAR), the rest of Central Luzon, CALABARZON, Occidental Mindoro, and Antique will see cloudy skies with scattered rain showers and thunderstorms.

From Wednesday to Friday, Aug. 12 to 14, the Ilocos Region, Abra, Benguet, Zambales, Bataan, and Occidental Mindoro may have cloudy skies with scattered rains and thunderstorms. Meanwhile, partly cloudy to cloudy skies are expected elsewhere in the Philippines, with isolated rain showers or thunderstorms likely, especially during the afternoon or evening.

The southwest monsoon is a seasonal wind system that typically brings rain to the western sections of the Philippines.

PAGASA officially announced the start of the habagat season in May 2026 after observing persistent southwesterly winds over the western part of the country. 

The rainy season subsequently began over the western sections of Luzon and the Visayas in early June. PAGASA noted that enhanced habagat rainfall over these areas could occur during this period.
