The Oceanic Niño Index (ONI) is a rolling 3-month average temperature anomaly, and used for tracking El Niño-Southern Oscillation climate patterns. Based on the latest data for the last 3 months (FMA), the Oceanic Nino Index is currently -0.16, signifying a La Nina period. A persistent above average sea surface temperature may signify an El Niño episode. Conversely, a below average sea surface temperature will signal the onset of La Nina occurences.
