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 Holroyd
Flood
Holroyd faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Holroyd is relatively low due to the urbanized nature of the suburb. However, surrounding bushland areas pose a potential threat, especially during dry and windy conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Holroyd experiences a high risk of heatwaves, particularly during summer months. Climate change is projected to increase the frequency and intensity of heatwaves, posing a significant threat to vulnerable populations.
Key drivers:
- ·Increased frequency of heatwaves
- ·Urban heat island effect
Coastal
Coastal risk is negligible in Holroyd due to its distance from the coastline.
Key drivers:
- ·Distance from coast

Detailed Hazard Analysis
heat Risk
Holroyd experiences a high risk of heatwaves, particularly during summer months. Climate change is projected to increase the frequency and intensity of heatwaves, posing a significant threat to vulnerable populations.
Primary Drivers
- ·Increased frequency of heatwaves
- ·Urban heat island effect
- ·Aging population
flood Risk
Holroyd faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development
- ·Inadequate drainage infrastructure
coastal Risk
Coastal risk is negligible in Holroyd due to its distance from the coastline.
Primary Drivers
- ·Distance from coast
bushfire Risk
Bushfire risk in Holroyd is relatively low due to the urbanized nature of the suburb. However, surrounding bushland areas pose a potential threat, especially during dry and windy conditions.
Primary Drivers
- ·Proximity to bushland
- ·Dry vegetation
- ·Windy conditions
What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to flood and heat risks.
Price Impact
Properties in flood-prone areas may experience price stagnation.
Buyer Checklist
- 1.Check flood maps
- 2.Assess home cooling options

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 Holroyd's Climate Risk Profile
Holroyd, located in western Sydney, is susceptible to several climate-related risks. Flooding is a significant concern due to the presence of local waterways and the potential for heavy rainfall events. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flooding.
Heatwaves also pose a considerable threat to Holroyd, especially during the summer months. The urban heat island effect exacerbates the impact of high temperatures, making it particularly challenging for vulnerable populations such as the elderly and those with chronic health conditions. The frequency and intensity of heatwaves are expected to rise in the coming decades.
While bushfire risk is relatively low compared to other areas in NSW, the proximity of bushland areas means that Holroyd is not entirely immune to this threat. Dry and windy conditions can increase the risk of bushfires spreading to the suburb.
Coastal risks are minimal in Holroyd due to its inland location. However, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, could still affect the suburb. Adapting to these challenges will require a coordinated effort from residents, businesses, and local government.
