Seasonal Climate Outlook

The BOM climate outlook was issued on 2 April 2020.

  • April rainfall is very likely to be above average for most of Australia (60–80% chance across southern Australia), except for parts of the east coast, seaward of the Great Dividing Range, which have roughly equal chances of wetter or drier conditions.
  • May to July is also likely to be wetter than average for much of western, central and southern Australia (mostly 60–75% chance).
  • April to June days are likely to be cooler across much of the southern mainland but nights are very likely to be warmer than average nationwide.
  • While recent rainfall over parts of eastern Australia has eased the dry in many areas, long-term rainfall deficiencies remain for many regions. Several months of above average rainfall may be required increase streamflows and replenish water storages. This outlook shows some possibility of further relief in the coming months.

Next update is expected on 9 April 2020

ENSO Outlook

The El Niño–Southern Oscillation (ENSO) Outlook was issued on 31 March 2020.

  • The tropical Pacific remains neutral with respect to the El Niño–Southern Oscillation (ENSO).
  • Six of the eight climate models surveyed by the Bureau indicate that ENSO is likely to stay neutral through the southern hemisphere winter, meaning it will have limited influence on Australian and global climate in the coming months. The remaining two models suggest La Niña conditions may develop during winter.
  • The Indian Ocean Dipole (IOD) is neutral. The IOD typically has little influence on Australian climate from December to April.
  • Recently the Southern Annular Mode (SAM) has been positive but is forecast to return to neutral levels over the next few days and then remain neutral for the following three weeks. SAM has little influence upon Australian rainfall in autumn.

The next update is expected on 14 April 2020
