About Wynnum's Climate Risk Profile

Wynnum, Western Australia, is a suburb that is increasingly vulnerable to the impacts of climate change. The region is expected to experience more frequent and intense heatwaves, increased rainfall intensity, and rising sea levels. These changes pose a significant threat to the local community and infrastructure.

Flooding is a major concern for Wynnum due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, leading to more frequent and severe floods. This can damage homes, businesses, and infrastructure, as well as disrupt transportation and essential services.

Heatwaves are also a growing threat to Wynnum. As global temperatures rise, the region is expected to experience more frequent and intense heatwaves. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions. It can also strain the electricity grid and increase the risk of bushfires.

Coastal inundation is another concern for Wynnum due to sea level rise. Rising sea levels can inundate low-lying coastal areas, damaging homes, businesses, and infrastructure. It can also erode beaches and other coastal features.

To mitigate these risks, it is important for residents and businesses in Wynnum to take steps to prepare for climate change. This includes investing in flood protection measures, such as raising homes and installing flood barriers. It also includes taking steps to reduce energy consumption and greenhouse gas emissions.
