PAGASA declares onset of amihan
Published · Updated
What happened
PAGASA announced that amihan has started, with strengthening high pressure over East Asia already bringing northeasterly winds and lower temperatures to Extreme Northern Luzon.
Why it matters
The onset of amihan changes near-term weather operations in northern Philippines, including marine conditions, rough-sea advisories, and cold-weather preparedness. It also affects planning for transport, fishing activity, and local government response over the next 24-72 hours.
PAGASA on October 28 declared the onset of the northeast monsoon, or amihan, citing strengthening high pressure over East Asia that is now driving northeasterly winds and lower temperatures over Extreme Northern Luzon. The declaration marks an operational shift for sea-state, fisheries, inter-island transport, and cold-surge planning in northern areas. It also changes the hazard mix that national and local disaster managers must plan for over the next several days as monsoon conditions interact with the ongoing very strong El Niño.
