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 McLaren Flat
Flood
McLaren Flat faces a moderate risk of flooding, primarily from heavy rainfall events and localised creek overflows. The risk is influenced by the topography and drainage infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
McLaren Flat has a high bushfire risk due to its proximity to bushland and prevailing dry conditions during summer. The risk is exacerbated by strong winds and potential ignition sources.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
McLaren Flat experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat events. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
McLaren Flat has a very low risk from coastal hazards due to its inland location. Sea level rise and coastal erosion are not significant concerns for this suburb.
Key drivers:
- ·Distance from the coast

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 McLaren Flat's Climate Risk Profile
McLaren Flat, located in South Australia, is subject to a range of climate-related risks. The primary concerns are flooding from intense rainfall events, bushfire risk due to surrounding vegetation, and increasing heatwave frequency.
The risk of flooding is influenced by the local topography and the capacity of existing drainage infrastructure. Intense rainfall events can lead to localised flooding, impacting properties and infrastructure. Climate change projections suggest an increase in rainfall intensity, potentially exacerbating flood risks in the future.
The suburb's proximity to bushland areas contributes to a significant bushfire risk, especially during the dry summer months. Factors such as dry vegetation, strong winds, and potential ignition sources increase the likelihood of bushfires impacting the community. Climate change is expected to worsen bushfire conditions, with longer fire seasons and more extreme fire weather.
Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions. The urban environment can amplify the effects of heatwaves, creating urban heat islands. Adaptation measures are needed to mitigate the impacts of extreme heat.
While coastal risks are minimal due to McLaren Flat's inland location, the community should still be aware of broader climate change impacts and contribute to mitigation efforts.
