An El Niño condition occurs
when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal
. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
