Philippines El Niño 2026 outlook
Warmer than average
Seasonal outlook
October to December 2026
Likely warmer than usual
The European seasonal forecast model expects the Philippines to average about 1.0°C warmer than usual for this time of year.
Estimated chance of each outcome. With no forecast signal, each would be about 1 in 3.
Technical details
- Model: ECMWF SEAS5 (system 51) ensemble mean, from the Copernicus Climate Data Store.
- 2 m air temperature anomaly: +1.02°C, averaged over October to December 2026, relative to the model's 1993 to 2016 average.
- Taken at the model grid point nearest 12.90, 121.80, so it represents that area rather than the whole country.
- Chances (cooler / about usual / warmer): 21% / 21% / 58%. Estimated by Niño Tracker from the size of the anomaly, because the ensemble mean product does not include the model's own odds.
- Confidence is set by the anomaly's size: under 0.5°C low, 0.5 to 1°C moderate, 1°C or more high.
El Niño right now
Very strong El Niño
El Niño is a natural warming of the central and eastern tropical Pacific Ocean that shifts weather patterns around the world. Over July to September 2026, sea temperatures there averaged about 2.2°C above normal, which counts as a very strong event.
Technical details
- Oceanic Niño Index (ONI): +2.16 for JAS 2026. It is the 3-month average sea surface temperature anomaly in the Niño 3.4 region (5°N to 5°S, 120°W to 170°W), from NOAA.
- El Niño conditions are +0.5°C or more, La Niña −0.5°C or less, sustained for five overlapping 3-month seasons. Strength: weak 0.5 to 0.9, moderate 1.0 to 1.4, strong 1.5 to 1.9, very strong 2.0 or more.
- NOAA now uses a relative version of this index (RONI) for official monitoring. The ONI is still published each month.

El Niño and Philippines: common questions
How will El Niño affect the Philippines in 2026?
The European seasonal forecast model expects the Philippines to average about 1.0°C warmer than usual for this time of year. The forecast covers October to December 2026. A strong signal. Outcomes usually follow it, but not always.
How does El Niño usually affect the Philippines?
Typical effects of past El Niño events in the Philippines: drier, warmer; drought risk. Every event is different, so these are tendencies rather than guarantees.
How does La Niña affect the Philippines?
Typical effects of past La Niña events in the Philippines: wetter, higher typhoon-season rainfall. La Niña often pushes weather roughly the opposite way to El Niño.
What is the weather forecast for the Philippines this week?
Over the next 7 days, forecast lows and highs are: Manila 26 to 33°C, Cebu City 24 to 31°C, Davao City 21 to 32°C, Baguio 15 to 24°C, Zamboanga City 25 to 31°C, Iloilo City 23 to 32°C, Cagayan de Oro 23 to 31°C and Bacolod 24 to 32°C. Across these cities the average is 25.9°C. Last year the same week averaged 25.4°C, so this week is forecast to be 0.5°C warmer.
Is El Niño happening right now?
El Niño is a natural warming of the central and eastern tropical Pacific Ocean that shifts weather patterns around the world. Over July to September 2026, sea temperatures there averaged about 2.2°C above normal, which counts as a very strong event. El Niño continues to strengthen, with a strong-to-very strong El Niño likely through January-March 2027 (remaining greater than an 83% chance).
