Learn moreAbout Augusta's Climate Risk Profile
Augusta, located in the south-west of Western Australia, is increasingly vulnerable to the impacts of climate change. The town's coastal location makes it particularly susceptible to sea level rise and coastal erosion, threatening infrastructure and natural ecosystems.
Flooding is another significant concern for Augusta, with the Blackwood River and nearby coastal areas posing a risk of inundation. Increased rainfall intensity and storm surges are expected to exacerbate this risk, potentially impacting homes, businesses, and transportation networks.
Rising temperatures and drier conditions are also contributing to an increased bushfire risk in the region. The surrounding bushland provides ample fuel for fires, and hotter, drier weather makes them more likely to ignite and spread rapidly.
While Augusta experiences moderate heat risk compared to other regions, increasing average temperatures and more frequent heatwaves can still impact vulnerable populations, such as the elderly and those with chronic health conditions. It is important to implement strategies to mitigate the effects of heat on public health and infrastructure.
Addressing these climate risks requires a comprehensive approach that includes adaptation measures to protect against the impacts of climate change, as well as mitigation efforts to reduce greenhouse gas emissions. By working together, the community can build a more resilient and sustainable future for Augusta.
