Heat Risk Analysis
Doubleview in Western Australia faces moderate 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 Doubleview 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.
CSIRO climate projections indicate that under a high-emissions scenario, many parts of Western Australia could experience a doubling in the number of days over 35 °C by 2050. For Doubleview, this means cooling costs and occupant comfort will become increasingly important considerations.
Get an address-level heat risk assessment from ClimateNest for Doubleview including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Climate projections show heat risk in Doubleview is tied to the broader Greater Perth climate. The suburb scores 6 on the 0–10 heat index, with the number of days above 35°C expected to grow through 2050 — a factor that affects cooling costs, garden viability and property desirability.
Doubleview located in Greater Perth (postcode 6018), is a Western Australia suburb tracked by ClimateNest. The suburb's median property value is $750,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Doubleview.

Frequently Asked Questions
How hot does Doubleview get in summer?
Doubleview in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Doubleview. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Doubleview?
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 Doubleview 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 Doubleview and the performance of your building envelope.
What heat mitigation measures work best in Doubleview?
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.
What are the main climate risks in Doubleview?
ClimateNest's suburb model rates Doubleview's dominant climate risk as extreme heat at 6/10 on a 0–10 index, followed by damaging wind (4/10) and bushfire (3/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Doubleview.
What share of Doubleview is exposed to high tropical cyclone risk?
ClimateNest's hazard overlay maps 8.5% of Doubleview in high-risk zones for tropical cyclone, with a further 73.6% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
