Learn moreAbout Perth CBD's Climate Risk Profile
Perth CBD, located in Western Australia, is susceptible to several climate-related risks. The suburb's proximity to the Swan River and the coast makes it vulnerable to flooding and coastal hazards. Rising temperatures and the urban heat island effect contribute to a high risk of heatwaves.
Flooding is a concern due to increased rainfall intensity and potential storm surges. Coastal erosion and sea level rise also pose a threat to infrastructure and property. While bushfire risk is relatively low, it is still a factor to consider.
Climate change projections indicate that these risks will intensify in the coming decades. Increased frequency and severity of extreme weather events are expected, impacting the livability and economic viability of Perth CBD.
Adaptation measures are crucial to mitigate these risks. These include improving drainage infrastructure, implementing heat mitigation strategies, and protecting coastal areas. Community awareness and preparedness are also essential for building resilience.
