Climate Hazard Breakdown for St Arnaud
Flood
St Arnaud faces a moderate risk of flooding, primarily from intense rainfall events and the overflow of local waterways. The town's location in a relatively flat area contributes to potential water accumulation.
Key drivers:
- ·Increased rainfall intensity
- ·Changes in land use
Bushfire
The bushfire risk in St Arnaud is moderate due to the surrounding grasslands and bushland. Hot, dry summers increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
St Arnaud experiences a high number of hot days during summer, increasing the risk of heat stress for vulnerable populations. Climate change is expected to exacerbate this issue.
Key drivers:
- ·Rising average temperatures
- ·More frequent heatwaves
Coastal
As an inland town, St Arnaud has a negligible risk from coastal hazards.

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout St Arnaud's Climate Risk Profile
St Arnaud, located in regional Victoria, is increasingly vulnerable to the impacts of climate change. The primary concerns are rising temperatures, increased frequency of heatwaves, and potential for flooding due to more intense rainfall events.
The town's geographical location makes it susceptible to both riverine and flash flooding. Changes in land use and aging infrastructure further exacerbate the flood risk. Residents should stay informed about weather warnings and have emergency plans in place.
Bushfire risk is also a concern, particularly during the dry summer months. The surrounding grasslands and bushland can fuel fires, posing a threat to properties and lives. Regular property maintenance and awareness of fire danger ratings are crucial.
Heatwaves are becoming more frequent and intense, placing vulnerable populations at risk. Ensuring access to cooling centers and implementing heat health plans are essential adaptation measures.
While St Arnaud is not directly impacted by coastal hazards, the broader effects of climate change, such as disruptions to supply chains and economic impacts, can still affect the community. Addressing these challenges requires a coordinated effort from residents, local government, and emergency services.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
