WHAT ABOUT LA NIÑA?

Most fishermen have heard of El Niño: a climate event where trade winds weaken and the equatorial warm-water band that occurs when the jet stream moves southeast into the central and east-central Pacific Ocean, specifically around the equator, is pushed eastward, toward the west coast. La Niña, however, is the counterpart of El Niño, and has opposite effect. Here, the trade winds blow harder than normal, pushing this warm-water pool westward, promoting cold-ocean upwellings to replace the departing warm water.

Collectively, El Niño and La Niña are part of a larger, natural climate fluctuation referred to as the El Niño Southern Oscillation.
