What is El Niño, and what does it mean for the Philippines?
El Niño is a warming of the tropical Pacific Ocean that shifts where rain falls. For the Philippines it usually means less rain, longer dry spells and hotter days, strongest from December to February. It is a natural cycle, not a storm — and PAGASA's latest advisory says a strong to very strong one is present now.
What causes it
A warm patch of ocean, thousands of kilometres away
The trade winds weaken
Normally, trade winds push warm surface water west, toward Asia and the Philippines. In an El Niño, those winds weaken or reverse. The warm water slides back to the central and eastern Pacific instead — thousands of kilometres east of us.
Rain follows the heat
Rain clouds form over the warmest water. When that warm pool sits in the central Pacific instead of near the Philippines, the rain that would normally fall on us falls over the ocean instead — leaving us drier than usual.
It is a cycle, not a crisis
El Niño and its opposite phase, La Niña, alternate every two to seven years. PAGASA and NOAA track the pattern using ocean temperature readings — that is how we know one is happening before the dry season even starts.
What it does to the Philippines
Six things that change while El Niño lasts
Less rain than usual
Dry spells can run longer and start earlier, especially from December to February.
Hotter, more humid days
Heat index climbs faster with less cloud cover and rain to cool things down.
Usually fewer, not zero
Storm tracks tend to shift further out to sea — but the Philippines can still get hit.

How we know
Three agencies, three readings, one event
PAGASA watches the Philippines' alert status; NOAA and IRI Columbia watch the ocean itself, in the Niño 3.4 region at the centre of the Pacific. The numbers differ because they measure slightly different things, not because anyone disagrees.
Strong to very strong El Niño present
Expected to peak before the end of 2026 and persist into the first quarter of 2027.

Common questions
The seven things people search for most about this El Niño.
Is there El Niño in the Philippines right now?
Yes. PAGASA's latest advisory says a strong to very strong El Niño is present and expected to last into the first quarter of 2027.
What does El Niño mean, in plain words?
It means the ocean near the equator in the central Pacific has warmed up, which pushes rain away from the Philippines and usually brings a hotter, drier stretch.
How strong is this El Niño?
Strong to very strong. IRI Columbia's weekly Niño 3.4 reading is +3.3 °C; the Australian BoM's relative reading is +2.88 °C — a record for that measure.
Is this a “Super El Niño”?
“Super El Niño” is a media label, not an official PAGASA category. PAGASA describes this event as strong to very strong.
How is El Niño different from La Niña?
Opposite phases of the same cycle. El Niño warms the central Pacific and dries the Philippines; La Niña cools it and usually brings more rain and a busier typhoon season.
Will Metro Manila run short of water?
Angat Dam is the level to watch. As of 5 Nov 2026 it sits 1.21 m below normal high but well above the rule curve — full detail on the water page.
When will this El Niño end?
PAGASA expects it to peak before the end of 2026 and persist into the first quarter of 2027. BoM's models keep readings above threshold into autumn 2027.
