How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Catherine Hill Bay's Climate Risk Profile
Catherine Hill Bay, located on the coast of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location makes it susceptible to rising sea levels and coastal erosion, threatening infrastructure and property.
Bushfire risk is also a significant concern due to the surrounding bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires, posing a direct threat to lives and property. Residents should maintain awareness and preparedness during bushfire season.
Heatwaves are projected to become more frequent and intense, impacting public health, particularly among vulnerable populations. It is important to stay informed about heatwave warnings and take necessary precautions to stay cool and hydrated.
Flooding, both from intense rainfall and coastal inundation, is another growing concern. Improved drainage and coastal protection measures are needed to mitigate the impacts of flooding. Residents should be aware of flood risks and have a plan in place.
Addressing these climate risks requires a coordinated effort from local government, emergency services, and the community. By taking proactive steps to adapt to climate change, Catherine Hill Bay can enhance its resilience and protect its unique character.
