La Nina Continues but May Be Declining
31st December 2022
The Bureau of Meteorology has advised that La Niña continues in the tropical Pacific, but some indicators show signs of declining strength.
La Niña typically increases the chance of above average rainfall for northern and eastern Australia during summer. Models suggest that ocean temperatures may reach ENSO-neutral levels during January or February 2023, and remain at neutral levels until at least April.
The Southern Annular Mode (SAM) is in a positive phase and is likely to be neutral to positive through January and February. During summer, a positive SAM increases the chance of above average rainfall for parts of eastern Australia and below average rainfall for western Tasmania.
