Heat Risk Analysis
Subiaco in Western Australia 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 Subiaco 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.
The urban heat island effect can increase temperatures by several degrees compared to surrounding areas.

Frequently Asked Questions
How hot does Subiaco get in summer?
Subiaco in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Subiaco. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Subiaco?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for Western Australia. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Subiaco 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 Subiaco and the performance of your building envelope.
What heat mitigation measures work best in Subiaco?
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.
