About Trewilga's Climate Risk Profile

Trewilga, NSW, is a rural locality that faces a range of climate-related challenges. The primary concerns are flooding, bushfires, and increasing temperatures. Changes in rainfall patterns and prolonged dry periods contribute to these risks.

Flooding can occur due to heavy rainfall events, particularly in areas near waterways. Bushfire risk is elevated due to the surrounding vegetation and dry conditions. Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations.

Climate change projections indicate that these risks will increase in the future. Higher temperatures, more intense rainfall, and longer periods of drought are expected. These changes will place additional stress on infrastructure and emergency services.

Adapting to these changes will require a combination of individual and community-level actions. This includes improving building resilience, managing vegetation, and developing emergency response plans. Collaboration between residents, local government, and emergency services is essential to ensure the safety and well-being of the community.
