La Nina

La Nina is a weather pattern involving the strong winds blowing the Pacific Ocean’s warm surface water from South America to Indonesia. With the warm water moving westwards, the cold water underneath rises to the surface near the coast of South America. This results in countries like Peru and Ecuador witnessing droughts and countries like Australia and Indonesia facing heavy precipitation. Its occurrence is less frequent when compared to El Nino.

After the La Nina conditions have ended, the NOAA has predicted a 67 per cent chance that neutral conditions would persist through the Summer. However, there is a 50 to 55 per cent chance that there will be a second-year La Nina this fall.
