By March of 1998, the region of unusually warm water associated with El Niño has started to shrink. Look at how the region of water with temperature greater than 4 C is now only about 75 meters deep along the coast of South America; in January, it was 150 meters deep, and the maximum temperature anomaly was over 11 C. Now the maximum temperatures are only 5 C warmer than usual.
