Heat Risk Analysis
Great Western in Victoria faces location-specific extreme heat risk. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since 1910, with the frequency of extreme heat days rising across most regions.
The urban heat island (UHI) effect can make built-up areas of Great Western warmer than surrounding rural areas, particularly on summer nights. Dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress that varies by property.
Elderly residents and those with chronic health conditions are particularly vulnerable during heatwaves.
Get an address-level heat risk assessment from ClimateNest for Great Western including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Heat risk in Great Western is tied to the broader Regional VIC climate, and the number of days above 35°C is expected to grow through 2050 - a factor that affects cooling costs, garden viability and property desirability.

Is extreme heat increasing in Great Western?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for Victoria. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Great Western properties?
Higher temperatures increase cooling demand, which raises electricity costs. ClimateNest provides energy cost projections based on your property's specific exposure to extreme heat days in Great Western and the performance of your building envelope.
What heat mitigation measures work best in Great Western?
Effective heat mitigation includes light-coloured roofing (cool roofs), ceiling and wall insulation, double-glazed windows, external shading, cross-ventilation design, and increasing tree canopy around the property. These measures reduce indoor temperatures and cooling costs.
