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 Mount Colah's Climate Risk Profile
Mount Colah, located in the Hornsby Shire, is characterized by its proximity to significant bushland, which contributes to a heightened bushfire risk. The suburb also experiences flooding from local creeks and heavy rainfall events. Climate change projections indicate an increase in both the frequency and intensity of extreme weather events, posing challenges for residents and infrastructure.
The primary climate risks for Mount Colah include bushfires, flooding, and heatwaves. Bushfire risk is driven by dry vegetation and strong winds, while flooding is exacerbated by increased rainfall intensity and urban development. Heatwaves are becoming more frequent and intense due to climate change, impacting vulnerable populations.
Future climate projections suggest that Mount Colah will experience hotter summers, more frequent heatwaves, and more intense rainfall events. These changes will increase the risk of bushfires and flooding, potentially impacting property values and insurance premiums. Residents should take proactive measures to adapt to these changes, such as implementing bushfire protection measures and improving stormwater drainage.
Understanding these risks and taking appropriate adaptation measures is crucial for ensuring the long-term resilience of Mount Colah. This includes individual actions, such as preparing emergency plans and maintaining properties, as well as community-level initiatives, such as improving infrastructure and implementing climate-smart planning policies.
