Learn moreAbout Kojonup's Climate Risk Profile
Kojonup, located in the Great Southern region of Western Australia, is vulnerable to several climate-related risks. The Blackwood River and surrounding creeks pose a flood risk during periods of heavy rainfall. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flooding events.
The region is also susceptible to bushfires, particularly during the hot, dry summer months. The extensive bushland surrounding Kojonup provides ample fuel for fires, and climate change is projected to increase the frequency and severity of bushfire conditions.
Heatwaves are another concern for Kojonup, with temperatures often exceeding 40°C during summer. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
While Kojonup is not directly exposed to coastal hazards, the broader region may experience indirect impacts from sea level rise and coastal erosion. It is important for residents to stay informed about climate risks and take steps to prepare for extreme weather events.
