Seasonal Climate Outlook

The BOM climate outlook, issued 23 January 2020 indicates:

The chances of a wetter or drier than average February to April are roughly equal for most of Australia, however, scattered parts of eastern Australia have a slightly increased chance of being drier than average.

Recent rainfall has been beneficial for some areas. However, while outlooks for drier than average conditions have eased compared to those issued for late 2019, several months of above average rainfall are needed to see a recovery from current long-term rainfall deficiencies.

Daytime temperatures for February to April are likely to be above average across almost all of Australia except  parts of the southwest and southern Tasmania. February to April nights are very likely to be warmer than average for most of the country.

Most climate influences are neutral, however, the long-term warming trend coupled with warm and dry soils are keeping temperature outlooks warmer than average.

The next update is expected on 30 January 2020 (pm)

ENSO Outlook

The El Niño–Southern Oscillation (ENSO) Outlook was issued on on 21 January 2020.

Both the ENSO and Indian Ocean Dipole (IOD) are neutral. When these main climate drivers are neutral, Australia’s climate can be influenced by more local or short-term climate drivers.

Tropical waters near and to the west of the Date Line remain warmer than average, potentially drawing some moisture away from Australia. Additionally, tropical cyclone Tino, in combination with the passage of the Madden-Julian Oscillation, has provided a burst of westerly winds in the western Pacific, with potential to further warm parts of the western Pacific in the coming week or two.

The IOD typically has little influence on Australian climate from December to April. However, the effects from the strong positive IOD event that occurred in the second half of 2019 persist, with the landscape primed for bushfire weather and heatwaves this summer.

Most climate models indicate ENSO will remain neutral until at least the end of the southern hemisphere autumn.

Next update is expected 4 February 2020
