Learn moreAbout Woy Woy's Climate Risk Profile
Woy Woy, situated on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. Its low-lying coastal geography makes it particularly susceptible to flooding from heavy rainfall, storm surges, and sea level rise. The community faces the challenge of adapting to these escalating risks to protect homes, infrastructure, and the natural environment.
Flooding is a major concern, with potential for inundation of residential and commercial areas during extreme weather events. The risk is exacerbated by the proximity to Brisbane Water and local waterways. Coastal erosion also threatens the shoreline, impacting property values and recreational spaces.
Rising temperatures and more frequent heatwaves pose a health risk, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions. Bushfire risk is also increasing due to hotter, drier conditions, threatening properties bordering bushland.
Addressing these challenges requires a coordinated effort involving local government, residents, and businesses. Implementing adaptation measures such as improved drainage, coastal protection works, and community education programs is crucial to building resilience and ensuring a sustainable future for Woy Woy.
