About Brocklesby's Climate Risk Profile

Brocklesby is a small town in the Greater Hume Shire of New South Wales. The primary climate risks for Brocklesby are flooding and heatwaves. The town is located near waterways that are prone to flooding during periods of heavy rainfall. Climate change is expected to increase the intensity and frequency of heavy rainfall events, leading to a higher flood risk.

Heatwaves are another significant concern for Brocklesby. The town experiences hot summers, and climate change is projected to increase average temperatures and the frequency of extreme heat events. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

Bushfire risk is moderate due to surrounding grasslands and bushland. While not as significant as flood and heat risk, it is still a factor to consider, especially during dry periods.

Coastal risks are negligible due to Brocklesby's inland location. Residents should focus on mitigating flood and heat risks through appropriate adaptation measures.
