Seasonal Climate Outlook
BoM Climate outlook (19 November 2020):
- December to February is likely to be wetter than average across most of northern Victoria and patches near Hamilton, Sale and Ballarat (greater than 70% chance). However, southern Victoria and parts of western Victoria have only a slight chance of being wetter than average (65-70 % chance). In south-western Victoria, Otway Coast, Geelong and Wonthaggi regions there is only a 60-65% chance of above average rainfall.
- Throughout December to February, days are expected to be warmer than average across most of Victoria (greater than 65% chance). North-eastern Victoria is likely to have days closer to average (55-65% chance). Victoria's southern coastline, Latrobe Valley region and the south western border region are very likely to be warmer than average (greater than 80% chance). Night-time temperatures are very likely to be warmer than average across Victoria (greater than 80% chance).

Climate Driver Update
BoM Climate Driver Update (24 November 2020):
- La Niña continues in the tropical Pacific. International climate models suggest it is likely to continue to at least through February 2021.
- Models suggest the current La Niña will strengthen, peaking in December 2020 or January 2021 at moderate to strong levels.
- La Niña typically increases the chance of above average rainfall across eastern Australia during summer. Climate outlooks indicate rainfall during December 2020 to January 2021 is likely to be above average for most of the country.
- The Southern Annular Mode (SAM) is currently neutral but is expected to increase to positive values over the next week. Positive values are expected at least into early 2021, and typically increase rainfall in south eastern Australia.
The next update is expected on 8 December 2020 (pm)
