Hazard Breakdown
Climate Hazard Breakdown for Guildford
Flood
Guildford is located near the Swan River and Helena River, making it susceptible to flooding. Riverine flooding can occur after periods of heavy rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·Rising river levels
Bushfire
While Guildford is primarily urban, some areas are adjacent to bushland, posing a moderate bushfire risk. Increased temperatures and drier conditions can exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Guildford experiences hot summers, and heatwaves are becoming more frequent and intense. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·More frequent heatwaves
Coastal
Guildford is located inland and is not directly exposed to 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 Guildford's Climate Risk Profile
Guildford, Western Australia, is a suburb with a rich history and a growing population. Its location near the Swan and Helena Rivers makes it vulnerable to flooding, particularly during periods of heavy rainfall. Climate change is expected to increase the intensity and frequency of these rainfall events, exacerbating the flood risk.
Rising temperatures and more frequent heatwaves also pose a significant threat to Guildford. The urban environment can amplify the effects of heat, creating an urban heat island effect. This can lead to increased health risks, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions.
While bushfire risk is lower compared to some other areas in Western Australia, Guildford is not immune. Areas adjacent to bushland are at risk, and drier conditions can increase the likelihood of bushfires. It is important for residents to be aware of bushfire safety measures and to maintain their properties to reduce fuel loads.
Coastal hazards are not a major concern for Guildford due to its inland location. However, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could still affect the suburb.
