Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Chester Hill
Flood
Chester Hill has a moderate risk of flooding due to its proximity to waterways and relatively flat terrain. Several historical flood events have impacted the area, and climate change is expected to increase the frequency and intensity of heavy rainfall events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Chester Hill has a relatively low risk of bushfire due to its urban environment and distance from large areas of bushland. However, there are still some risks associated with vegetation in parks and gardens, and extreme heat and dry conditions can increase the risk.
Key drivers:
- ·Vegetation management
- ·Urban density
Heat
Chester Hill is expected to experience more frequent and intense heatwaves in the future due to climate change. This will increase the risk of heat stress and other health problems, particularly for vulnerable populations such as the elderly and people with chronic diseases.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Chester Hill is located a significant distance from the coast and has a very low risk of coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Distance from coast

Primary Drivers
- ·Climate change
- ·Urban heat island effect
- ·Lack of green space
flood Risk
Chester Hill has a moderate risk of flooding due to its proximity to waterways and relatively flat terrain. Several historical flood events have impacted the area, and climate change is expected to increase the frequency and intensity of heavy rainfall events.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development
- ·Inadequate drainage infrastructure
coastal Risk
Chester Hill is located a significant distance from the coast and has a very low risk of coastal hazards such as sea level rise and coastal erosion.
Primary Drivers
- ·Distance from coast
bushfire Risk

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 Chester Hill's Climate Risk Profile
Chester Hill, located in the western suburbs of Sydney, is susceptible to several climate-related risks. The most significant of these is flooding, due to its location near waterways and relatively flat topography. Historical flood events have caused damage to property and infrastructure in the area, and climate change is projected to increase the frequency and intensity of heavy rainfall events, further exacerbating this risk.
Heatwaves are another significant concern for Chester Hill. As climate change progresses, the suburb is expected to experience more frequent and intense heatwaves, which can pose a serious threat to public health, particularly for vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can further amplify the impact of heatwaves.
Bushfire risk is relatively low in Chester Hill due to its urban environment. However, there is still some risk associated with vegetation in parks and gardens, and extreme heat and dry conditions can increase the risk of bushfires spreading into the suburb.
Coastal hazards are not a significant concern for Chester Hill due to its distance from the coast. However, climate change may have indirect impacts on the suburb, such as through changes in weather patterns and increased demand for resources.
