Hazard Breakdown
Climate Hazard Breakdown for Willetton
Flood
Willetton faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. The risk is projected to increase slightly due to climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Willetton has a notable bushfire risk due to its proximity to bushland areas. Hot, dry summers and strong winds exacerbate the potential for bushfires. Climate change is expected to further increase the frequency and intensity of bushfire events.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Willetton experiences moderately high temperatures during summer, with the potential for heatwaves. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Willetton is located a significant distance inland and has a very low risk of coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Distance from the coast
Wind
Moderate wind risk — winter storms
Storm
Moderate storm risk — occasional severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — cooling demand in summer

Learn moreAbout Willetton's Climate Risk Profile
Willetton, a suburb of Perth, Western Australia, is primarily threatened by bushfires and heatwaves, with a secondary risk of flooding. The suburb's proximity to bushland increases its vulnerability to bushfires, especially during the hot, dry summer months. Climate change is projected to increase the frequency and intensity of bushfire events, posing a significant threat to property and human safety.
Heatwaves are another significant concern for Willetton. Rising average temperatures and more frequent heatwave events can lead to heat stress and other health problems, particularly for vulnerable populations such as the elderly and those with pre-existing medical conditions. The urban heat island effect can further exacerbate these risks.
Flooding is a less significant but still present risk for Willetton. Heavy rainfall events can overwhelm drainage systems and lead to localized flooding. Climate change is expected to increase rainfall intensity, potentially increasing the risk of flooding in the future.
Coastal hazards are not a significant concern for Willetton due to its distance from the coast. Sea level rise and coastal erosion are unlikely to directly impact the suburb.
Residents and property owners in Willetton should take steps to mitigate these risks, such as maintaining their properties to reduce bushfire fuel loads, preparing for heatwaves, and ensuring they have adequate insurance coverage.
