The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) declared the end of the southwest monsoon on Monday, October 5, 2026. This marks the conclusion of a prolonged weather pattern that brought heavy rains and strong winds across the country.
Pagasa stated the monsoon’s retreat follows a period of increased typhoon activity, including the influence of Typhoon Choi-wan. The agency reported that the trough associated with the typhoon contributed to scattered rains in the Visayas and Mindanao on October 4. These rains were part of the broader weather system affecting the region.
The southwest monsoon, which typically lasts from May to November, has been active earlier than usual this year. Pagasa noted that the early end of the monsoon season is linked to shifting atmospheric conditions and the movement of tropical cyclones. This change has impacted rainfall patterns, leading to both drought in some areas and flooding in others.
The agency continues to monitor weather developments and issue updates as needed. The end of the monsoon season is expected to bring a shift in weather patterns, with drier conditions likely in the coming weeks.
