About Swanbourne's Climate Risk Profile

Swanbourne, Western Australia, faces a range of climate-related risks, with coastal hazards being the most prominent concern. The suburb's location near the coast makes it vulnerable to sea level rise, storm surges, and coastal erosion. These factors could impact property values and infrastructure in the long term.

While the flood risk is relatively low, localized heavy rainfall events can still cause temporary inundation. Residents should ensure their properties have adequate drainage and be aware of flood warnings.

Bushfire risk is moderate, requiring residents to maintain their properties and be prepared for potential bushfire events, especially during dry periods. Staying informed about fire danger ratings and having a bushfire plan is crucial.

Heat risk is increasing, with projections indicating higher average temperatures and more frequent heatwaves. Vulnerable populations, such as the elderly and those with chronic health conditions, should take extra precautions during hot weather.

Overall, Swanbourne requires a proactive approach to climate adaptation, focusing on coastal protection, flood management, bushfire preparedness, and heatwave response.
