Expect cooler days ahead as the northeast monsoon season, locally known as “amihan,” is officially here.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced on Tuesday, Nov. 19 that the amihan will bring a steady drop in temperatures, particularly over the next few weeks.

PAGASA explained that the strengthening high-pressure area over Siberia has triggered a surge of northeasterly winds, which are expected to affect the northern part of Luzon starting on Tuesday, following the passage of Super Typhoon Pepito.

It added that these winds, along with successive surges expected over the next two weeks, will cause an increase in atmospheric pressure and a further cooling of surface air temperatures.

As the amihan intensifies, the northeasterly wind flow will dominate most of the country, bringing cooler and drier air. 

The public can also expect colder temperatures, more frequent wind surges, and rougher seas, particularly along Luzon's coastal areas, in the coming months.

PAGASA defines the amihan as a cold wind that originates from mainland Asia, typically prevailing from November to March, with its peak occurring between December and February. 

This seasonal wind not only ushers in cooler temperatures but also brings rain, particularly to the eastern side of the country.
