Global sea temperature anomaly

This image shows the current anomaly (deviation from normal) of the surface temperature of Earth's oceans. Purple and blue areas indicate areas where the water is colder than normal, while orange and red areas signify where the water temperature is higher than normal. Yellow areas have a temperature that is nearly the same as in past years.
