The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that the country's weather on Friday, December 26, 2025, will continue to be influenced by two major weather systems. The northeast monsoon, locally known as amihan, and the easterlies are expected to bring varied conditions across the archipelago, from isolated rains to potentially hazardous winds and seas.
Weather Impacts Across Luzon
In its 4 a.m. advisory, PAGASA stated that the northeast monsoon will have the most pronounced effect on extreme Northern Luzon. Batanes and the Babuyan Islands are forecast to have cloudy skies with rains. The state weather bureau warned that this could lead to flash floods or landslides in these vulnerable island provinces.
Meanwhile, mainland Cagayan, Isabela, and Apayao will experience cloudy skies with light rains due to the amihan, though PAGASA assesses this will have "no significant impact." For Metro Manila and the rest of Luzon, residents can expect partly cloudy to cloudy skies with isolated light rains brought by the prevailing cool winds.
Visayas, Mindanao, and Coastal Conditions
The eastern parts of the country will feel the effects of a different system. Visayas, Mindanao, and Palawan are predicted to have partly cloudy to cloudy skies with isolated rain showers or thunderstorms. These conditions are caused by the warm and humid easterlies.
PAGASA also issued a marine weather warning. Extreme Northern Luzon will experience strong to gale-force northeast winds, resulting in rough to very rough seas, posing risks to mariners. The rest of northern Luzon will have moderate to strong winds and moderate to rough coastal waters. For the rest of the country, conditions will be milder with light to moderate northeast winds and slight to moderate seas.
No Tropical Cyclone Threat
In a reassuring note for the post-Christmas period, PAGASA confirmed that as of 4 a.m., no low-pressure areas are being monitored inside or outside the Philippine Area of Responsibility (PAR) for possible tropical cyclone development. This indicates a stable large-scale weather pattern, with the monsoon and easterlies as the primary drivers of the day's conditions.
The public, especially those in Batanes and the Babuyan Islands, are advised to remain vigilant against possible rain-induced hazards. All seafarers navigating the waters of extreme Northern Luzon should take necessary precautions due to the dangerous sea conditions.
