The initial blast of cold breeze coming from the northeasterly surface wind flow over some parts of Northern Luzon signifies that the country is moving towards the transition phase from southwest monsoon or “habagat” to northeast monsoon or “amihan” season.


“May pattern na (na papunta na sa transition). May precursor na ng amihan dahil sa northeasterly surface wind flow (ibig sabihin) papunta na sa phase ng transition. (There is already a pattern that we are going towards the transition period. There is already a precursor of the northeast monsoon or ‘amihan’ which is the presence of the northeasterly surface wind flow. It means we are already going to the transition phase),” Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) weather specialist Joey Figuracion said in a phone interview.

In its weather bulletin issued on Monday morning, PAGASA said the northeasterly surface wind flow will bring partly cloudy to cloudy skies with isolated light rains over Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Abra, Benguet, Ifugao, Kalinga, Mountain Province, Apayao, Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino.

Figuracion said the southwest monsoon or “habagat” is still existing but will gradually weaken as the wind pattern transitions to northeast monsoon or “amihan” season.

“Unti-unting hihina ang habagat base sa global pattern na ino-observe natin. (The southwest monsoon will gradually weaken based on the global pattern that we are observing,” he added.

He said the “amihan,” which is known for surges of cold weather, will likely begin by the end of October or early November. It usually reaches its peak from December to February, when cold surges occur.

Last year, the “amihan” season kicked in on October 25.

The northeast monsoon is defined by PAGASA as cold winds from the northeast that bring rains over the eastern side of the country.
