Sea Surface Temperature Anomalies
show La Niña, El Niño and Normal Conditions in the Pacific Ocean

Sea Surface Temperature Anomaly is the amount the Sea Surface Temperature differs from the normal value for the month (in degrees Centigrade).

  • La Niña, a colder-than-normal event, is indicated by blue colors in the plot.
  • Normal conditions are indicated by green color in the plots.
  • El Niño, a warmer-than-normal event, is indicated by red colors in the plot.

The data are from the Reynolds Sea Surface Temperature (SST) analysis from the National Center for Environmental Prediction (NCEP) for the entire Pacific Ocean (70N to 70S).

Graphics are provided by the TAO project and created by Dai McClurg.

You can also see animations of the Reynolds SST and TAO buoy SST from the TAO realtime data page.
