Frequently asked questions

What is the ONI?

The Oceanic Niño Index is NOAA's official El Niño / La Niña indicator: the 3-month running mean of sea surface temperature anomalies in the Niño 3.4 region (5°N–5°S, 170°W–120°W), relative to a 30-year base period updated every 5 years.

How do I read the table?

Each cell is a 3-month season (DJF = December–February, and so on). Red cells are at or above +0.5 °C (El Niño conditions) and blue cells at or below −0.5 °C (La Niña conditions); darker means stronger.
