About Catherine Hill Bay's Climate Risk Profile

Catherine Hill Bay, located on the coast of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location makes it susceptible to rising sea levels and coastal erosion, threatening infrastructure and property.

Bushfire risk is also a significant concern due to the surrounding bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires, posing a direct threat to lives and property. Residents should maintain awareness and preparedness during bushfire season.

Heatwaves are projected to become more frequent and intense, impacting public health, particularly among vulnerable populations. It is important to stay informed about heatwave warnings and take necessary precautions to stay cool and hydrated.

Flooding, both from intense rainfall and coastal inundation, is another growing concern. Improved drainage and coastal protection measures are needed to mitigate the impacts of flooding. Residents should be aware of flood risks and have a plan in place.

Addressing these climate risks requires a coordinated effort from local government, emergency services, and the community. By taking proactive steps to adapt to climate change, Catherine Hill Bay can enhance its resilience and protect its unique character.
