Climate

The Bureau of Meteorology provide a number of various tools to look at forecast rainfall including:

Rainfall Observation
Map of daily, weekly and monthly rainfall observations can show potential inflows.
Rainfall Forecast
Raw data from their computer models to estimate 5 day rainfall amounts. Useful to use in combination with local area forecasts.
Rainfall Outlook
A longer term outlook looking ahead up to 3 months.
ENSO Outlook
La Niña, a negative IOD and a positive SAM all point to a wetter forecast for the eastern coast.
Landscape Water Balance
This can provide an insight to what runoffs can be expected with rain. If there is a water deficit, much of any rainfall will be sucked up by the dry soil, before feeding the creeks and streams.

Recent Climate Observations / Trends

Where possible, weather statistics are based on the 30 years between 1990 and 2020. Canberra observations started in 2008. Deciles are 1 to 9, meaning these figures exclude the lowest and highest 10% of observations. i.e. they are normalised to exclude the extreme values.

Temperature

Canberra is 3° to 4°C cooler than the lower sections between Jugiong and Balranald. Expect a 1.5° to 2°C decrease in temperature around the source that is 1,000 m higher than Canberra. Snow is likely in winter.

In the lower sections, Wagga Wagga reflects a very similar climate to Gundagai, and there is a very slight increase in temperature as you head out west to Balranald (1° to 2°C).

Rainfall

In the upper catchments, rainfall is more common in the summer months albeit the spring snow melt in the main driver of the alpine creek flows. It is interesting to note that in the last 30 years that in the western slopes around Wagga Wagga, the winter rains have been higher than the summer rains. Out west the rainfalls are definitely more sporadic.
