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 Broughton
Flood
Port Broughton faces a moderate risk of flooding, primarily from heavy rainfall events and storm surges. The risk is expected to increase with climate change due to more intense rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Port Broughton is relatively low compared to other regions in South Australia. However, dry vegetation and strong winds can still pose a threat during the fire season.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Port Broughton is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Port Broughton is vulnerable to coastal erosion and inundation due to sea level rise and storm surges. The low-lying coastal areas are particularly at risk.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Broughton's Climate Risk Profile
Port Broughton, located on the Yorke Peninsula in South Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and storm surges, heatwaves, and coastal erosion due to sea level rise.
The risk of flooding is expected to increase as rainfall intensity rises and storm surges become more frequent. Low-lying areas near the coast are particularly vulnerable. Heatwaves are also becoming more common and intense, posing a threat to public health, especially for vulnerable populations.
Coastal erosion is another significant concern, with sea level rise threatening to inundate low-lying areas and damage infrastructure. The local council is working to implement adaptation measures to mitigate these risks, but further action is needed.
Residents and property owners should take steps to prepare for these climate-related hazards, including developing emergency plans, investing in flood protection measures, and ensuring adequate insurance coverage. Staying informed about the latest climate projections and adaptation strategies is crucial for building resilience in Port Broughton.
