Learn moreAbout Manly's Climate Risk Profile
Manly, a coastal suburb in New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include coastal erosion, flooding, heatwaves, and bushfires.
Sea level rise poses a significant threat to Manly's beaches and coastal infrastructure. Increased storm surges can inundate low-lying areas, causing damage to property and disrupting daily life. Coastal erosion is already evident in some areas, and this is expected to worsen with rising sea levels.
Heatwaves are becoming more frequent and intense, particularly during the summer months. The urban heat island effect exacerbates the problem, leading to elevated temperatures and increased heat stress for residents. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk.
Flooding is another concern, especially during periods of heavy rainfall. Low-lying areas are susceptible to flash flooding, which can damage property and disrupt transportation. Climate change is expected to increase the intensity of rainfall events, further increasing the risk of flooding.
While bushfire risk is relatively low compared to other parts of NSW, areas bordering bushland are still vulnerable. Dry vegetation and strong winds can create conditions conducive to bushfires, posing a threat to homes and businesses.
