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 Whyalla
Flood
Whyalla faces a moderate risk of flooding, primarily from intense rainfall events and stormwater runoff. The flat terrain and limited natural drainage can exacerbate flooding in certain areas.
Key drivers:
- ·Intense rainfall
- ·Stormwater runoff
Bushfire
The risk of bushfire in Whyalla is relatively low compared to other regions in South Australia, but still present due to surrounding vegetation and dry conditions during summer months.
Key drivers:
- ·Dry vegetation
- ·Hot summers
Heat
Whyalla experiences high temperatures during summer, leading to a significant risk of heatwaves and heat stress, particularly for vulnerable populations.
Key drivers:
- ·High summer temperatures
- ·Heatwaves
Coastal
Whyalla is located on the coast and is exposed to coastal hazards such as sea level rise and coastal erosion. These hazards pose a significant threat to infrastructure and coastal ecosystems.
Key drivers:
- ·Sea level rise
- ·Coastal erosion

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 Whyalla's Climate Risk Profile
Whyalla, located on the coast of South Australia, is particularly vulnerable to the impacts of climate change. The region is already experiencing the effects of rising temperatures, with more frequent and intense heatwaves posing a significant threat to public health and infrastructure.
Sea level rise is another major concern for Whyalla, as it could lead to increased coastal erosion and inundation of low-lying areas. This could damage coastal ecosystems, infrastructure, and residential properties. The frequency and intensity of storm surges are also expected to increase, further exacerbating coastal hazards.
Inland, Whyalla is also susceptible to flooding from intense rainfall events. The flat terrain and limited natural drainage can cause stormwater to accumulate quickly, leading to flash flooding in urban areas. Climate change is expected to increase the frequency and intensity of these rainfall events, further increasing the risk of flooding.
While the risk of bushfire is relatively lower compared to other regions, it is still a concern, especially during dry summer months. Changes in temperature and rainfall patterns could increase the risk of bushfires in the future. Addressing these climate risks requires a comprehensive approach that includes mitigation, adaptation, and community engagement.
