Time to dust off those jackets as the northeast monsoon, or “amihan,” season officially begins in the country.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday, Oct. 27 declared the onset of the amihan season, following the intensification of a high-pressure area over East Asia, which has pushed cool northeasterly winds to reach the northern Philippines.
“Over the past few days, observations have indicated the strengthening of a high-pressure area over East Asia, which has caused a surge of northeasterly winds over extreme Northern Luzon,” PAGASA said in its advisory.
The weather bureau added that increasing atmospheric pressure, the cooling of surroundings, and other meteorological conditions “indicate the start of the northeast monsoon season.”
PAGASA said the amihan is expected to become more dominant in most parts of the country, bringing cool and dry air and occasional cold temperature surges.
It also warned that successive monsoon surges over the next two weeks may result in rough sea conditions over the seaboards of Northern Luzon.
The amihan season generally begins in late October or early November and lasts until early March, while the southwest monsoon or “habagat” season typically starts in the latter half of May or early June and persists until October.
