About Frenchs Forest's Climate Risk Profile

Frenchs Forest, located on the Northern Beaches of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, particularly during the dry summer months. Climate change is expected to exacerbate these conditions, leading to more frequent and intense bushfire seasons.

Flooding is another significant concern for Frenchs Forest. Heavy rainfall events can overwhelm local drainage systems, leading to flash flooding in low-lying areas. The increasing intensity of rainfall due to climate change is likely to increase the frequency and severity of these events.

Rising temperatures and heatwaves also pose a risk to the community, especially vulnerable populations such as the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify these risks in densely built-up areas.

While coastal risks are relatively low due to the suburb's distance from the immediate coastline, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, can still affect the community. Proactive adaptation measures are essential to mitigate these risks and ensure the long-term resilience of Frenchs Forest.
