About Hexham's Climate Risk Profile

Hexham is situated in a low-lying area adjacent to the Hunter River, making it susceptible to flooding during periods of heavy rainfall. Climate change projections indicate an increase in the frequency and intensity of extreme rainfall events, which could lead to more frequent and severe flooding in the area. The local council and emergency services are working to improve flood management infrastructure and preparedness.

In addition to flooding, Hexham is also vulnerable to heatwaves during the summer months. As temperatures rise due to climate change, the risk of heat stress and heatstroke will increase, particularly for vulnerable populations such as the elderly and those with chronic health conditions. Residents are advised to take precautions during heatwaves, such as staying hydrated and seeking air-conditioned environments.

Bushfire risk in Hexham is relatively low compared to other parts of NSW, but the risk could increase as climate change leads to hotter and drier conditions. Grass fires are a potential concern, and residents should maintain their properties to reduce the risk of fire.

Coastal risks are minimal in Hexham due to its distance from the open coast. Sea level rise is not expected to have a significant direct impact on the suburb.
