Seasonal Climate Outlook
BoM Climate outlook (6 May 2021):
June to August is likely to be slightly wetter than average for most of Victoria (50-70% chance of exceeding the median). Central and north-central regions are expected to be wetter than average (greater than 70% chance).
June to August maximum temperatures are likely to be warmer than average across the state (greater than 60% chance), except in north-western Victoria where temperatures are expected to be closer to average. June to August minimum temperatures are also expected to be much warmer than average across Victoria (greater than 75% chance). Western Victoria is slightly warmer than average (65-75% chance).

Climate Driver Update
BoM Climate Driver Update (11 May 2021):
The El Niño–Southern Oscillation (ENSO) continues at neutral levels. Climate model outlooks currently indicate this neutral phase will last at least until October. As such, the Bureau's ENSO Outlook is INACTIVE.
Oceanic indicators of ENSO persist at neutral levels, with Pacific sea surface temperatures close to the long-term average across most of the equatorial region. Atmospheric indicators such as the Southern Oscillation Index and cloud patterns are also close to average.
The Madden–Julian Oscillation is over the Indian Ocean region. It is forecast to move eastwards across Australian longitudes over the coming fortnight.
The Southern Annular Mode (SAM) has been positive for the past week. It is expected to remain positive for the coming fortnight. SAM typically has little influence on Australian rainfall during autumn, but may have a drying influence for parts of south-west and south-east Australia over the coming fortnight.
The Indian Ocean Dipole is currently neutral and likely to remain neutral during the first half of winter.
The next update is expected on 25 May 2021 (pm)
