The Oceanic Niño Index (ONI) has traditionally been NOAA's official measure, or index, to track the El Niño-Southern Oscillation (ENSO). The ONI is calculated as the rolling 3-month average sea surface temperature departure from average (anomaly) in the east-central tropical Pacific Ocean. The warmer-than-average phase of ENSO is called El Niño, the cooler-than-average phase is called La Niña,
