El Niño and La Niña (Oceanic Niño Index)
Graph Summary

Seasonal (3-month) sea surface temperatures in the central tropical Pacific Ocean compared to the 1981-2010 average. Warming or cooling of the ocean surface near the International Dateline is one of the criteria used to monitor the El Niño-La Niña climate pattern. Data from NOAA CPC.

Image Summary

Difference from average sea surface temperature across the tropical Pacific Ocean during a strong El Niño (top) and a strong La Niña (bottom). During El Niño, the east-central tropical Pacific is warmer than average. During La Niña, the region is colder than average. Data from NOAA NCEI.

Teaser Summary

The ONI tracks the warming or cooling of surface waters in the tropical Pacific Ocean that indicate El Niño and La Niña.

Graph of seasonal ONI values

Seasonal (3-month) sea surface temperatures in the central tropical Pacific Ocean compared to the 1981-2010 average. Warming or cooling of at least 0.5˚Celsius above or below average near the International Dateline is one of the criteria used to monitor the El Niño-La Niña climate pattern.

Two global maps comparing ocean temperature anomalies during an El Niño and La Niña

Sea surface temperature across the tropical Pacific Ocean in December 1997 (top), during a strong El Niño, and in December 1988 (bottom) during a strong La Niña. The ONI only tracks the temperatures in the Niño3.4 region, but during strong events, the entire central and eastern tropical Pacific will generally become warmer or cooler than average. Maps by NOAA Climate.gov, based on data from NOAA's Physical Science Lab.
