Seasonal Climate Outlook
The climate outlook issued 28 November 2019 indicatesa drier than average summer is likely for eastern Australia.
A drier than average summer is likely for eastern Australia.
Above average daytime temperatures are very likely this summer.
Summer nights likely to be warmer than average except in the southeast.
A strong positive Indian Ocean Dipole (IOD) and periods of negative Southern Annular Mode (SAM) continue to influence the outlook, increasing the likelihood of warmer and drier conditions for large parts of Australia. Both influences are expected to progressively weaken, then dissipate during the first half of the season.
The next update is expected on 5 December 2019 (pm)
View the full outlook on the BOM Website.
ENSO Outlook
The El Niño–Southern Oscillation (ENSO) Outlook was issued on 26 November 2019.
ENSO remains neutral while the strong positive Indian Ocean Dipole (IOD) continues.
International climate models surveyed indicate the positive IOD is likely to be slower to decline than usual, and may persist into mid-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.
Most climate models forecast ENSO-neutral conditions for the rest of 2019 and into the first quarter of 2020.
Next update is expected 10 December 2019
