Climate Risk in Parramatta, New South Wales
Parramatta faces moderate climate risks, primarily from flooding and heatwaves. Its location on the Parramatta River floodplain makes it vulnerable to riverine flooding, while the urban environment exacerbates heat during summer. Climate change is expected to increase the frequency and intensity of these hazards.

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 Parramatta
Flood
Parramatta is located on the Parramatta River floodplain, making it susceptible to riverine flooding. Intense rainfall events can cause the river to overflow, inundating low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development reducing natural drainage
Bushfire
While Parramatta is primarily an urban area, it has some interface with bushland, particularly along its western and northern edges. Bushfire risk is present but relatively lower compared to more heavily forested areas.
Key drivers:
- ·Dry vegetation
- ·Increased frequency of heatwaves
Heat
Parramatta experiences high temperatures during summer, and heatwaves are becoming more frequent and intense. The urban heat island effect exacerbates the problem, particularly in densely built-up areas.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Parramatta is located inland and is not directly exposed to coastal hazards such as sea level rise and coastal erosion. However, sea level rise can affect the Parramatta River's tidal range.
Key drivers:
- ·Sea level rise
- ·Changes in tidal patterns

Detailed Hazard Analysis
heat Risk
Parramatta experiences high temperatures during summer, and heatwaves are becoming more frequent and intense. The urban heat island effect exacerbates the problem, particularly in densely built-up areas.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Parramatta is located on the Parramatta River floodplain, making it susceptible to riverine flooding. Intense rainfall events can cause the river to overflow, inundating low-lying areas.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development reducing natural drainage
- ·Sea level rise impacting river flow
coastal Risk
Parramatta is located inland and is not directly exposed to coastal hazards such as sea level rise and coastal erosion. However, sea level rise can affect the Parramatta River's tidal range.
Primary Drivers
- ·Sea level rise
- ·Changes in tidal patterns
bushfire Risk
While Parramatta is primarily an urban area, it has some interface with bushland, particularly along its western and northern edges. Bushfire risk is present but relatively lower compared to more heavily forested areas.
Primary Drivers
- ·Dry vegetation
- ·Increased frequency of heatwaves
- ·Wind patterns

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 Parramatta's Climate Risk Profile
Parramatta, a major commercial and residential hub in Sydney, is increasingly exposed to climate-related risks. The suburb's location on the Parramatta River floodplain makes it particularly vulnerable to flooding, with intense rainfall events capable of causing significant inundation. Climate change is projected to increase rainfall intensity, further elevating flood risk.
Heatwaves are another significant concern for Parramatta. The urban heat island effect, caused by the concentration of buildings and paved surfaces, traps heat and raises temperatures, especially during summer. As climate change drives up average temperatures and increases the frequency of heatwaves, Parramatta's residents will face greater heat stress.
While Parramatta is not directly on the coast, sea level rise can affect the Parramatta River's tidal range and potentially exacerbate flooding. Bushfire risk is present but relatively lower compared to more heavily forested areas.
Addressing these climate risks requires a multi-faceted approach, including improved flood management infrastructure, urban greening initiatives to mitigate the urban heat island effect, and community awareness programs to prepare residents for extreme weather events. Adaptation measures are crucial to protect Parramatta's residents, businesses, and infrastructure from the impacts of climate change.
