Seasonal Climate Outlook

  • The BOM climate outlook was updated on 25 June 2020
  • July rainfall is likely be below average for parts of southeast Australia
  • August to October turns wetter with the three month period likely to be wetter than average for much of northern and eastern Victoria, while the south-east and central areas have a roughly equal chance of being wetter or drier.
  • Both days and nights during July to September are likely to be warmer than average across Australia.
  • Next update is expected on 2 July 2020 (pm)

Climate Driver Update

  • The Climate Driver Update was issued on 23 June 2020.
  • Both the El Niño–Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) remain neutral. However, cooling in the tropical Pacific Ocean has continued, and the majority of models anticipate this cooling will be close to the threshold for La Niña by early spring.
  • Consequently, the Bureau's ENSO Outlook has shifted to La Niña WATCH. This means the chance of La Niña forming in 2020 is around 50%—roughly double the average likelihood.
  • Despite recent cooling in the eastern Indian Ocean, three of six models continue to suggest the possibility of a negative IOD developing during winter or early spring.
  • The Southern Annular Mode (SAM) is currently positive and is forecast to remain positive for the remainder of June and early July. During winter, a positive SAM typically means less rainfall for southwest Western Australia, southern Victoria, and Tasmania.
  • The Madden–Julian Oscillation (MJO) is currently weak, and is not expected to influence Australia's climate in the coming fortnight.
  • The next update is expected on 7 July 2020 (pm)

On 23 June 2020 the ENSO Wrap–Up changed its name to the Climate Driver Update, recognising that the ENSO Wrap–Up has long provided more than just ENSO information. BoM will continue to provide fortnightly updates on the current state of the Pacific and Indian oceans, covering ENSO and the IOD, but will also include more information about drivers from the Southern Ocean and tropics—the Southern Annular Mode and Madden–Julian Oscillation.
