Learn moreAbout Exmouth's Climate Risk Profile
Exmouth, located in the Gascoyne region of Western Australia, is increasingly vulnerable to the impacts of climate change. The town's coastal location and arid climate make it particularly susceptible to a range of hazards, including bushfires, heatwaves, coastal erosion, and flooding.
Bushfire risk is a significant concern, with the surrounding dry vegetation providing ample fuel for fires during the hot, dry summer months. Climate change is expected to exacerbate this risk by increasing temperatures and prolonging drought periods. Residents should be aware of bushfire safety measures and have evacuation plans in place.
Heatwaves are also becoming more frequent and intense, posing a threat to public health, particularly for vulnerable populations such as the elderly and those with chronic health conditions. It is important to stay hydrated, seek air-conditioned environments, and avoid strenuous activity during heatwaves.
Coastal erosion and inundation are also major concerns, as sea level rise and storm surges threaten to erode beaches, damage infrastructure, and inundate low-lying areas. The town's coastal location makes it particularly vulnerable to these impacts.
Flooding can occur from heavy rainfall events and storm surges, causing damage to property and infrastructure. It is important to be aware of flood warnings and take steps to protect your property.
