About Wollongong's Climate Risk Profile

Wollongong, a coastal city in New South Wales, is increasingly vulnerable to the impacts of climate change. Rising sea levels, more frequent and intense heatwaves, and changes in rainfall patterns are all contributing to the risks faced by the community.

Flooding is a significant concern for Wollongong, with both riverine and coastal flooding posing threats. Intense rainfall events can overwhelm drainage systems, leading to flash flooding in urban areas. Sea level rise exacerbates coastal flooding, increasing the risk of inundation during storm surges.

Bushfire risk is also present, particularly in areas bordering bushland. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Residents need to be prepared and aware of the risks during the bushfire season.

Heatwaves are becoming more frequent and intense in Wollongong, posing a health risk to vulnerable populations, such as the elderly and those with chronic illnesses. The urban heat island effect can further amplify temperatures in built-up areas.

Coastal erosion is another significant challenge for Wollongong, with rising sea levels threatening beaches and coastal infrastructure. Protecting the coastline and managing coastal development are crucial for mitigating the impacts of climate change.
