About Windsor's Climate Risk Profile

Windsor, located on the Hawkesbury River floodplain, is highly vulnerable to flooding. The Hawkesbury-Nepean Valley is a unique geographical area where several major rivers converge, creating a high flood risk for communities like Windsor. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events.

Bushfire risk is also a concern for Windsor, with surrounding bushland creating a potential ignition source. Hotter, drier conditions are expected to lengthen the bushfire season and increase fire intensity. Residents should maintain their properties and be prepared to evacuate if necessary.

Heatwaves are another significant threat to Windsor, with high temperatures during summer posing a risk to vulnerable populations. Climate change is projected to increase the frequency and intensity of heatwaves, exacerbating this risk. It is important to stay hydrated and seek shelter during heatwaves.

While coastal hazards are not a direct threat to Windsor due to its inland location, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, could still affect the community. Residents should be aware of these potential impacts and take steps to prepare.
