( Supplied: Bureau of Meteorology) La Niña is therefore typically associated with wetter than average conditions for northern and eastern Australia, particularly in winter, spring and early summer.
How often does La Nina occur?
“La Niña and El Niño generally have a three to seven year cycle so we are not expecting to see another event like this develop at the end of the year.
What is a La Nina weather pattern?
The La Nina weather system over summer is typically associated with greater rainfall, more tropical cyclones and cooler than average temperatures in the Pacific Ocean region. Australia is likely to see heavy rainfall, floods and tropical cyclones this summer with a La Nina event declared.

Are we in a La Niña or El Nino?
As things stand with the El Niño-Southern Oscillation (ENSO), neutral conditions are currently present in the tropical Pacific and favored to last through the North American summer and into the fall.
What are the effects of La Niña?
The effects of La Niña are experienced globally. With catastrophic floods, hurricanes and cyclones in countries on the western part of the Pacific and, on the other hand, bushfires and droughts along the west coast of the USA and East Africa, farms are adversely affected, and crops can be produced as expected.

El Niño and La Niña episodes typically last 9-12 months. They both tend to develop during the spring (March-June), reach peak intensity during the late autumn or winter (November-February), and then weaken during the spring or early summer (March-June).
