Seasonal Climate Outlook
BoM Climate Outlook (25 May 2023):
- June to August rainfall is likely to be below average across northern and western Victoria (<20%-25% chance of exceeding the median), with a slightly higher chance of exceeding the median in southern Victoria (30-45% chance of exceeding the median).
- Maximum temperatures in June to August are very likely to be warmer than average across the whole of Victoria (>80% chance of exceeding the median).
- Minimum temperatures in June to August are also likely to be warmer than average across southern Victoria (>80% chance of exceeding the median), with the chance of exceeding the median decreasing to 50-65% towards the north.
- The next update is expected on 1 June 2023.
Climate Driver Update
BoM Climate Driver Update (23 May 2023):
- The ENSO Outlook remains at El Niño WATCH. This means there is a 50% chance (twice the normal likelihood) of an El Niño in 2023.
- ENSO is currently neutral. When ENSO is neutral, the Pacific Ocean typically exerts little influence on Australian climate patterns.
- When the ENSO Outlook has reached El Niño WATCH, El Niño has subsequently developed in about half of those years. El Niño typically suppresses rainfall in eastern Australia during the winter and spring months.
- The Indian Ocean Dipole (IOD) is currently neutral. Models suggest a positive IOD event developing in winter. A positive IOD typically supresses winter and spring rainfall and if it occurs with El Niño, it can exacerbate El Niño's drying effect.
- The next update is expected on 6 June 2023.
Current urban restrictions
As at 25 May 2023, there were no towns on restrictions, with permanent water saving rules in place across Victoria.

Quarterly groundwater level trend summary
Groundwater level trend update - 1 October to 31 December 2022 quarter.
Groundwater level trends in groundwater management units (GMUs) are reported quarterly. Groundwater level trends for GMUs have been determined based on 5 years (short-term) or 10 years (long-term) consistent monitoring data from key bores in the State Observation Bore Network (SOBN) (Glossary).
Go to the DEECA website for more information on SOBN and GMUs.
| TREND | GMU type | Declining | Stable | Rising |
|---|---|---|---|---|
| Short-term trend | GMA | 3 | 15 | 20 |
| WSPA | 1 | 2 | 7 | |
| Short-term total | 4 | 17 | 27 | |
| Long-term trend | GMA | 6 | 20 | 12 |
| WSPA | 3 | 3 | 4 | |
| Long-term total | 9 | 23 | 16 | |
Note: Insufficient data or monitoring bores were available to determine a short-term and long-term trend in 5 GMAs.

Groundwater management unit short-term trends - October to December 2022 quarter
The map below shows the short-term (5-year) trends in each GMU (both GMAs and WSPAs) across Victoria. The trends are determined using the data from the SOBN key bores in the second map below.

Seasonal determinations and allocations
Seasonal determinations are made against water shares to provide allocations in declared systems. In northern Victoria, Goulburn-Murray Water makes the seasonal determinations in the relevant systems, while Southern Rural Water makes the seasonal determinations in the Thomson/Macalister and Bacchus Marsh/Werribee systems.
In the Grampians Wimmera Mallee Water area, resource assessments are undertaken every month to determine the amount of water that can be made available to entitlement holders. These monthly assessments result in a formal announcement on water allocations.
Coliban Water assess seasonal allocations for customers on its rural network based on available resources in the Coliban System.
