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 Carnac
Flood
Carnac faces a low risk of flooding, primarily from heavy rainfall events. The island's relatively small size limits the potential for significant flooding.
Key drivers:
- ·Rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire on Carnac is very low due to its limited vegetation and island geography. The surrounding ocean acts as a natural firebreak.
Key drivers:
- ·Vegetation dryness
- ·Wind patterns
Heat
Carnac experiences moderate heat risk, with potential for heatwaves during the summer months. The island's exposed location can exacerbate heat effects.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Carnac faces a low risk from coastal hazards, primarily due to sea level rise and potential erosion. The island's low elevation makes it vulnerable to these changes.
Key drivers:
- ·Sea level rise
- ·Storm surge

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 Carnac's Climate Risk Profile
Carnac Island, located off the coast of Western Australia, presents a unique climate risk profile due to its island geography and limited development. The island's small size and low elevation make it particularly susceptible to the impacts of sea level rise and coastal erosion.
While the risk of bushfire is minimal due to the lack of significant vegetation, the island does experience moderate heat risk during the summer months. Heatwaves can pose a threat to visitors and the island's ecosystem. The risk of flooding is also relatively low, but heavy rainfall events can still cause localized flooding.
Climate change projections indicate a gradual increase in heat risk and coastal hazards over the coming decades. Sea level rise is expected to exacerbate erosion and inundation, while rising temperatures will increase the frequency and intensity of heatwaves.
Given its unique environment, adaptation measures are essential to protect Carnac Island from the impacts of climate change. These measures should focus on coastal protection, heat mitigation, and sustainable management of the island's natural resources.
