About Serpentine's Climate Risk Profile

Serpentine, Western Australia, is situated in a region that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity and proximity to the Serpentine River, as well as more frequent and intense heatwaves.

The risk of flooding is exacerbated by the potential for river overflow and inadequate drainage infrastructure. Bushfire risk is also a concern, given the surrounding bushland and the potential for drier conditions and higher temperatures to increase the likelihood and intensity of fires.

Heatwaves pose a significant threat to vulnerable populations, such as the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify the impact of heatwaves in built-up areas.

While coastal risks are minimal due to Serpentine's inland location, the broader region is still affected by climate change impacts. Adaptation measures are needed to mitigate these risks and protect the community.
