The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) confirmed the conclusion of the habagat season, citing observable changes in prevailing atmospheric conditions and the strengthening of competing weather systems.

The southwest monsoon, which typically brings significant rainfall to western portions of the country during summer months, has been a defining feature of the Philippine climate cycle. The seasonal winds and accompanying precipitation patterns influence agricultural planning, water resources, and emergency preparedness across the region.

Weather bureau officials noted that the transition marks a shift toward different atmospheric conditions as the country enters a new phase of its annual weather cycle. Residents and sectors dependent on monsoon patterns are advised to monitor Pagasa updates for information about upcoming weather developments and any systems that may affect the archipelago.

The timing of monsoon transitions can vary year to year based on broader climate patterns. Pagasa continues to track atmospheric developments and will provide regular forecasts to assist communities in planning and preparing for seasonal weather changes.
