Learn moreAbout Kewdale's Climate Risk Profile
Kewdale, located in Western Australia, is primarily exposed to risks associated with increasing temperatures and changes in rainfall patterns. The urban environment exacerbates the heat island effect, leading to higher average temperatures and more frequent heatwave events. This poses a significant threat to vulnerable populations, including the elderly and those with pre-existing health conditions.
Flooding is another concern for Kewdale, particularly due to localized heavy rainfall events. The suburb's relatively flat topography and existing drainage infrastructure may struggle to cope with increased rainfall intensity, leading to potential property damage and disruption to daily life.
While the risk of bushfire is relatively low due to the urbanized nature of Kewdale, it is not entirely absent. Dry vegetation in parks and reserves can still pose a localized threat, especially during prolonged periods of hot and dry weather. Residents should remain vigilant and take appropriate precautions to minimize the risk of fire.
Coastal hazards are not a significant concern for Kewdale due to its inland location. However, the broader impacts of climate change, such as disruptions to supply chains and increased energy costs, may still indirectly affect the suburb.
