Hazard Breakdown
Climate Hazard Breakdown for Hamilton Hill
Flood
Hamilton Hill faces a moderate risk of flooding, primarily from intense rainfall events and potential stormwater runoff. The area's relatively flat topography can exacerbate flooding in low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Hamilton Hill has a high bushfire risk due to its proximity to bushland areas. Hot, dry summers and strong winds can create dangerous conditions, increasing the likelihood of bushfires impacting the suburb.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Hamilton Hill experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat events. This can pose health risks, especially for vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Hamilton Hill faces a high risk from coastal hazards due to its proximity to the coastline. Sea level rise and storm surges can lead to coastal erosion and inundation, threatening properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
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 Hamilton Hill's Climate Risk Profile
Hamilton Hill, located in Western Australia, is exposed to a range of climate-related risks that are projected to intensify in the coming decades. The suburb's coastal location makes it particularly vulnerable to sea level rise and storm surges, which can lead to coastal erosion and inundation of low-lying areas.
Bushfire risk is also a significant concern for Hamilton Hill, given its proximity to bushland areas. Hot, dry summers and strong winds create ideal conditions for bushfires, which can pose a direct threat to properties and human safety. Residents need to be vigilant during the bushfire season and take steps to prepare their homes and families.
Heatwaves are becoming more frequent and intense in Hamilton Hill, driven by rising global temperatures and the urban heat island effect. This can lead to heat stress and other health problems, especially for vulnerable populations such as the elderly and those with chronic illnesses.
Flooding is another risk factor for Hamilton Hill, particularly during periods of heavy rainfall. The suburb's topography and drainage systems can exacerbate flooding in certain areas, potentially causing damage to properties and infrastructure. It is important for residents to understand their flood risk and take appropriate precautions.
