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 Augusta
Flood
Port Augusta faces a moderate risk of flooding due to its location near Spencer Gulf and the occasional heavy rainfall events. The risk is exacerbated by low-lying areas within the suburb.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Port Augusta is moderate, with surrounding scrubland posing a threat during hot and dry conditions. Increased temperatures and drier vegetation contribute to the risk.
Key drivers:
- ·Increased temperatures
- ·Drier vegetation
Heat
Port Augusta experiences high heat risk due to its inland location and hot, dry summers. Heatwaves are becoming more frequent and intense, impacting vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·More frequent heatwaves
Coastal
Port Augusta faces a significant coastal risk due to its location on Spencer Gulf. Sea level rise and storm surges threaten low-lying areas and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm surge 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 Augusta's Climate Risk Profile
Port Augusta is located at the head of Spencer Gulf, making it susceptible to a range of climate-related hazards. Rising sea levels and increased storm surge intensity pose a significant threat to coastal areas, potentially impacting infrastructure and property.
Heatwaves are becoming more frequent and intense, placing stress on vulnerable populations and increasing energy demand for cooling. The urban heat island effect exacerbates these impacts in built-up areas.
Changes in rainfall patterns are contributing to increased flood risk, particularly in low-lying areas. Heavy rainfall events can overwhelm drainage systems, leading to property damage and disruption.
Bushfire risk is also a concern, with surrounding scrubland posing a threat during hot and dry conditions. Increased temperatures and drier vegetation contribute to the risk of bushfires spreading rapidly.
Addressing these climate risks requires a combination of adaptation and mitigation measures, including improved infrastructure, community awareness programs, and efforts to reduce greenhouse gas emissions.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.

Frequently Asked Questions
What are the main climate change risks for Port Augusta?
Port Augusta faces significant risks from rising sea levels, increased storm surge, more frequent and intense heatwaves, and changes in rainfall patterns leading to increased flood risk.
How will rising sea levels affect Port Augusta?
Rising sea levels will increase the risk of coastal inundation, particularly in low-lying areas, potentially impacting infrastructure, property, and ecosystems.
What can I do to prepare for heatwaves in Port Augusta?
Stay hydrated, seek air-conditioned environments, check on vulnerable neighbors, and follow advice from local health authorities.
Where can I find information about flood risks in Port Augusta?
You can find flood maps and information on the WaterConnect website and from the City of Port Augusta council.
How is the City of Port Augusta addressing climate change?
The City of Port Augusta is developing and implementing climate adaptation strategies to address the risks posed by climate change, including infrastructure upgrades and community awareness programs. Check their website for details.
What is the urban heat island effect and how does it affect Port Augusta?
The urban heat island effect is when urban areas experience higher temperatures than surrounding rural areas due to the absorption of heat by buildings and pavement. This can exacerbate the impacts of heatwaves in Port Augusta.
