Hazard Breakdown
Climate Hazard Breakdown for Silverton
Flood
Silverton faces a moderate risk of flooding, primarily from intense rainfall events that can overwhelm local drainage systems. The risk is exacerbated by the arid climate and infrequent but heavy downpours.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Silverton is at high risk of bushfires due to its location in a sparsely vegetated, arid region with hot, dry summers. The surrounding scrubland provides ample fuel for fires, and strong winds can quickly spread flames.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Silverton experiences extreme heat, with very high average maximum temperatures during summer. Heatwaves are common and pose a significant risk to vulnerable populations.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Silverton is located far inland and has a negligible risk of coastal hazards.
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Learn moreAbout Silverton's Climate Risk Profile
Silverton, located in the arid outback of New South Wales, is highly vulnerable to the impacts of climate change. The primary risks are bushfires and extreme heat, driven by increasing temperatures and prolonged dry periods. The sparse vegetation surrounding the town provides ample fuel for bushfires, which can spread rapidly under strong winds.
Extreme heat is already a significant concern in Silverton, with average maximum temperatures frequently exceeding 40°C during summer. Heatwaves are common and can pose a serious threat to public health, especially for elderly and vulnerable residents. Climate change is expected to further increase the frequency and intensity of heatwaves, exacerbating this risk.
Flooding is a less frequent but still important risk. Intense rainfall events can overwhelm the local drainage systems, leading to flash flooding. The arid landscape means that water runoff is rapid, increasing the potential for damage.
While Silverton is far from the coast, coastal hazards are not a direct concern. However, the broader impacts of climate change, such as disruptions to supply chains and increased migration, could indirectly affect the town. Addressing these climate risks will require a combination of adaptation measures, such as improving bushfire preparedness, enhancing heatwave response plans, and upgrading drainage infrastructure.
