Learn moreAbout Narrabeen's Climate Risk Profile
Narrabeen, located on the Northern Beaches of Sydney, is vulnerable to several climate change impacts. The suburb's proximity to Narrabeen Lagoon and the coast makes it susceptible to flooding from heavy rainfall and rising sea levels. Heatwaves are also a significant concern, with temperatures projected to increase in the coming decades, posing risks to public health, especially for the elderly and those with pre-existing conditions.
Bushfire risk is present due to the surrounding bushland, although it is less severe than in some other parts of NSW. Coastal erosion is an ongoing issue, and sea level rise is expected to exacerbate this problem, threatening beachfront properties and infrastructure.
The Northern Beaches Council is developing strategies to mitigate these risks, including improving drainage infrastructure, implementing coastal management plans, and promoting community awareness. However, individual preparedness is also crucial for residents to protect themselves and their properties.
Climate projections indicate that Narrabeen will experience more frequent and intense extreme weather events in the future. This includes more severe heatwaves, increased rainfall intensity, and rising sea levels. These changes will have significant implications for the suburb's environment, economy, and community.
Adapting to these changes will require a collaborative effort from all levels of government, as well as the active participation of residents and businesses. By taking proactive measures, Narrabeen can build resilience and minimize the impacts of climate change.
