A Brief Overview of El Niño

El Niño is the warm phase that develops in the eastern tropical Pacific Ocean. It is part of a larger climate pattern known as the ENSO (El Niño-Southern Oscillation). On the flip side, La Niña is the cold phase of this phenomenon.

The name El Niño actually comes from Spanish, meaning "the little boy", based on the name of the newborn baby Jesus Christ. It is named since this warm phase tends to occur around Christmas.


Impacts of El Niño on the Weather

Why does El Niño make the weather hot? This is because warm ocean waters spread closer to the surface and release heat into the atmosphere. This released heat is what causes hot air.

It is important to note that El Niño affects sea temperatures and local weather, ranging from Australia to South America and surrounding regions. The intensity of El Niño varies from 4–5°F to 14–18°F. This intensity is measured by the Oceanic Niño Index (ONI) used by scientists.


El Niño in Indonesia 2023

The World Meteorological Organization predicts that El Niño will become stronger. Supari, the Coordinator of Climate Variability Analysis at the Indonesian Meteorology, Climatology, and Geophysics Agency (Badan Meteorologi, Klimatologi dan Geofisika/BMKG), said, "For the period up to November 2023, El Niño is likely still at a moderate level, but NOAA has stated that there is a more than 70% chance that El Niño will become strong." 

This strong El Niño is expected to occur in the fall, around December, January, and February. However, its impact in Indonesia is expected to diminish as the rainy season begins. "The period of strong El Niño is predicted to be short and will coincide with the autumn season, when Indonesia has already entered the rainy season. Therefore, the impact of this strong El Niño in Indonesia will decrease," said Supari.
