About Forrestfield's Climate Risk Profile

Forrestfield, located in Western Australia, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, especially during the hot, dry summer months. Rising temperatures and prolonged heatwaves pose a significant threat to the health and well-being of residents, particularly the elderly and those with pre-existing health conditions.

Flooding is another concern for Forrestfield, with heavy rainfall events capable of causing localized flooding. The increasing intensity of rainfall due to climate change is expected to exacerbate this risk. While coastal hazards are not a direct threat due to the suburb's inland location, the broader regional impacts of climate change can still affect Forrestfield.

The local council and community are taking steps to address these challenges, including implementing bushfire mitigation strategies, improving stormwater drainage, and developing heatwave response plans. However, more comprehensive and coordinated action is needed to effectively manage the growing risks.

Residents should be aware of the potential impacts of climate change and take proactive measures to protect themselves and their properties. This includes preparing for bushfires, developing a flood plan, and taking steps to stay cool during heatwaves. Staying informed about local weather conditions and emergency alerts is also crucial.
