Learn moreAbout Central Macdonald's Climate Risk Profile
Central Macdonald, located in the Hawkesbury region of New South Wales, is particularly vulnerable to the impacts of climate change, especially flooding. The suburb's proximity to the Hawkesbury River makes it susceptible to riverine flooding, which is expected to worsen with increased rainfall intensity.
Bushfire risk is also a concern, with surrounding bushland posing a moderate threat. Drier conditions and higher temperatures could lead to more frequent and intense bushfires, impacting the community and environment.
Heatwaves are projected to become more frequent and severe, potentially affecting vulnerable populations and straining infrastructure. Residents should prepare for extended periods of high temperatures.
While coastal hazards are not a direct threat, the overall impact of climate change requires proactive adaptation measures to protect the community and its assets. These measures include improving flood defenses, managing bushfire risks, and implementing strategies to mitigate the effects of heatwaves.
