Seasonal Climate Outlook

The BoM Climate outlook for October 2019 to December 2019 was issued on 10 October 2019:

Rainfall is likely to be below average across most of the country, excluding northern WA, for the remainder of October and November. The dry outlook for southern and northeastern Australia continues into December.

Daytime temperatures are likely to be above average across Australia for all outlook periods, with a spell of hot weather likely in mid-to-late October for most areas. Nights are likely to be warmer than average for most of Australia except in the southeast during November.

A positive Indian Ocean Dipole (IOD) is likely to remain the dominant climate driver for Australia until at least the end of spring. A prolonged period of negative SAM (Southern Annular Mode) may also contribute to the dry/warm outlooks for eastern Australia during October and November.

The next update is expected on 17 October 2019

ENSO Outlook

The El Niño–Southern Oscillation (ENSO) Outlook was issued on 15th October 2019.

ENSO remains neutral.

A strong positive Indian Ocean Dipole (IOD) continues to influence Australian and global climate.

The current positive Indian Ocean Dipole event has strengthened significantly over the past month. The IOD may strengthen further over the next fortnight. However, international climate models surveyed by the Bureau indicate the positive IOD is unlikely to persist far into summer. 

Typically, a positive IOD brings below average winter–spring rainfall to southern and central Australia, with warmer days for the southern two-thirds of the country. Positive IOD events are often associated with a more severe fire season for southeast Australia.

Climate models forecast neutral ENSO for the remainder of 2019 and into the first quarter of 2020. When ENSO is neutral, it has little effect on Australian and global climate, meaning other influences are more likely to dominate.

View the full outlook on the BOM Website.

The next update is expected on 29th October 2019.
