Learn moreAbout Scarborough's Climate Risk Profile
Scarborough, a coastal suburb in Western Australia, is increasingly vulnerable to the impacts of climate change. Rising sea levels, more frequent and intense heatwaves, and increased rainfall intensity are all contributing to the suburb's overall risk profile.
The primary concern for Scarborough is coastal erosion and inundation. Sea level rise is expected to exacerbate these issues, threatening infrastructure, properties, and recreational areas along the coastline. Storm surges can also cause significant damage, particularly during periods of high tide.
Heatwaves are becoming more frequent and intense in Scarborough, posing a risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect can further amplify these risks, particularly in densely built-up areas.
While bushfire risk is relatively low compared to other parts of Western Australia, some areas of Scarborough near parks and reserves may be vulnerable. It is important for residents to maintain their properties and be aware of bushfire safety guidelines.
Addressing these climate risks will require a coordinated effort from local government, residents, and businesses. Adaptation measures, such as coastal protection works, improved drainage infrastructure, and heatwave preparedness plans, are essential to protect the community and ensure the long-term sustainability of Scarborough.
