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 Port MacDonnell
Flood
Port MacDonnell faces a moderate risk of flooding, primarily from heavy rainfall and coastal inundation. The flat coastal terrain and proximity to the ocean increase vulnerability.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfire in Port MacDonnell is relatively low compared to other regions in South Australia, but still present due to surrounding vegetation.
Key drivers:
- ·Dry vegetation
- ·Wind patterns
Heat
Port MacDonnell experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected.
Key drivers:
- ·Global warming
- ·Urban heat island effect (minimal)
Coastal
Port MacDonnell is exposed to coastal risks, including sea level rise, coastal erosion, and storm surges. The low-lying coastal areas are particularly vulnerable.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Port MacDonnell's Climate Risk Profile
Port MacDonnell, a coastal town in South Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and rising sea levels, as well as coastal erosion and storm surges. While the risk of bushfire is relatively lower, it is still a factor to consider.
The town's low-lying coastal geography makes it particularly susceptible to sea level rise. Projections indicate that coastal inundation will become more frequent and severe in the coming decades, potentially impacting infrastructure and property.
Rising temperatures and more frequent heatwaves also pose a threat to the community's health and well-being. The elderly and other vulnerable populations are especially at risk during extreme heat events.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. This includes investing in improved drainage infrastructure, implementing coastal protection measures, and reducing greenhouse gas emissions. Community awareness and preparedness are also crucial for minimizing the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
