Learn moreAbout Parraweena's Climate Risk Profile
Parraweena, located in the Sutherland Shire of New South Wales, is exposed to a range of climate-related risks. The suburb's proximity to waterways and bushland makes it particularly vulnerable to flooding and bushfires. Climate change is expected to exacerbate these risks, with more intense rainfall events and prolonged periods of hot, dry weather.
Flooding is a significant concern for Parraweena, especially in low-lying areas. Intense rainfall can overwhelm drainage systems and lead to flash flooding, causing damage to property and infrastructure. Sea level rise also poses a threat to coastal areas, increasing the risk of inundation during storm surges.
The risk of bushfires is also high in Parraweena, given its location near bushland. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Residents need to be prepared for bushfire season and take steps to protect their homes and families.
Heatwaves are becoming more frequent and intense in Parraweena, posing a health risk to vulnerable populations. The urban heat island effect can further exacerbate the impact of heatwaves, making it essential for residents to stay cool and hydrated during hot weather.
Addressing these climate risks requires a coordinated effort from residents, local government, and emergency services. By taking proactive measures to adapt to climate change, Parraweena can build resilience and protect its community.
