March to May daytime temperatures are likely to be above average for southern, central and eastern Victoria (greater than 55% chance). Northern and north western Victoria are expected to be average (50 – 55% chance). Night time temperatures are expected to be higher than average across all of Victoria (greater than 65% chance), particularly in the south and east of the state (greater than 80% chance).

Climate Driver Update

BoM Climate Driver Update (2 March 2021):

The 2020–21 La Niña has passed its peak and is now weakening.

Climate model outlooks indicate the El Niño–Southern Oscillation (ENSO) will return to neutral during autumn, that is, neither La Niña nor El Niño.

Atmospheric indicators such as the Southern Oscillation Index, cloudiness near the Date Line and trade winds clearly remain at La Niña levels.

The Southern Annular Mode (SAM) has returned to neutral values, a neutral SAM has little influence on Australian rainfall.

The next update is expected on 16 March 2021 (pm)
