Seasonal Climate Outlook

The BoM Climate outlook for August to October 2019 was issued on 25 July 2019:

The outlook suggests a drier than average three months is likely for large parts of Australia. 

August to October daytime temperatures are likely to be warmer than average virtually nationwide, with very high chances for the northern half of the country.

Nights are likely to be warmer than average for much of Australia. However, parts of the southern mainland have roughly equal chances of warmer or cooler nights.

With more cloud-free days and nights expected, there is an increased risk of frost in susceptible areas.

Climate influences include a forecast positive Indian Ocean Dipole and weakening El Niño-Southern Oscillation-neutral tropical Pacific.

The next update is expected on 15 August 2019

ENSO Outlook

The El Niño–Southern Oscillation (ENSO) Outlook was issued on 6th August 2019.

The ENSO outlook is INACTIVE. The El Niño–Southern Oscillation (ENSO) remains neutral so the Indian Ocean Dipole (IOD) is likely to remain the key influence on Australia’s climate for the coming months.

The IOD index rose back above the positive IOD threshold this week. Climate models forecast positive IOD conditions for the remainder of winter and spring.

Typically, a positive IOD brings below average winter–spring rainfall to southern and central Australia, and above average daytime temperatures for the southern two-thirds of Australia

View the full outlook on the BOM Website.

The next update is expected on 20th August 2019.
