About Guilderton's Climate Risk Profile

Guilderton, located at the mouth of the Moore River in Western Australia, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location and proximity to bushland make it susceptible to a range of climate-related hazards.

Flooding is a significant concern, with the potential for both riverine and coastal inundation. Heavy rainfall events can cause the Moore River to overflow, while storm surges and sea level rise can lead to coastal flooding. These events can damage properties and disrupt infrastructure.

Bushfire risk is also elevated, particularly during the hot, dry summer months. The surrounding bushland provides ample fuel for fires, and strong winds can quickly spread flames towards residential areas. Residents need to be vigilant and prepared to evacuate if necessary.

Heatwaves are becoming more frequent and intense, posing a threat to public health. Older adults, young children, and people with chronic illnesses are particularly vulnerable to heat stress. It is important to stay hydrated, seek air-conditioned environments, and avoid strenuous activity during heatwaves.

Coastal erosion is another growing concern, as sea level rise and increased storm intensity threaten to erode beaches and damage coastal infrastructure. This can have significant economic and social impacts, as well as ecological consequences.
