About Northwood's Climate Risk Profile

Northwood, located on the Lower North Shore of Sydney, faces a number of climate-related challenges. The suburb's proximity to the Lane Cove River makes it susceptible to flooding, particularly during periods of heavy rainfall. Climate change is expected to exacerbate this risk, with more intense rainfall events predicted for the region.

Heatwaves are also a growing concern for Northwood. As global temperatures rise, the suburb is likely to experience more frequent and prolonged periods of extreme heat. This can have significant impacts on public health, particularly for vulnerable populations.

Sea level rise poses another threat to Northwood, especially for properties located close to the Lane Cove River. Coastal inundation and erosion could become more common in the future, potentially damaging infrastructure and property.

While Northwood is not considered a high-risk area for bushfires, it is still important to be aware of the potential threat, especially in areas bordering bushland. Residents should take steps to prepare their properties and have a bushfire survival plan in place.

Addressing these climate risks will require a coordinated effort from local government, residents, and businesses. By taking proactive steps to adapt to climate change, Northwood can protect its community and ensure a sustainable future.
