Heat Risk Analysis
Wembley in Western Australia faces elevated 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 Wembley 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 number of days exceeding 35°C is projected to increase in the coming years.
Get an address-level heat risk assessment from ClimateNest for Wembley including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Wembley (postcode 6014) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (8.9% of land in high-risk zones), surface flood (7.7% of land in high-risk zones), tropical cyclone (6.7% of land in high-risk zones). Exposure is not uniform across Wembley — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
Local Hazard Evidence
Historical Events
Another significant heatwave impacted Perth, with temperatures reaching record highs. This event highlighted the increasing vulnerability of the city to extreme heat.
Perth experienced a prolonged heatwave in February 2011, with temperatures exceeding 40°C for several consecutive days. This event placed significant strain on the electricity grid and caused heat-related illnesses.
Adaptation & Mitigation Actions
Improve building design for heat resilience
Near-termEncourage the use of passive cooling techniques, such as shading and natural ventilation, in new and existing buildings. Promote the installation of solar panels and energy-efficient appliances to reduce energy consumption during heatwaves.
Est. cost: Medium
Enhance drainage infrastructure
Near-termUpgrade stormwater drainage systems to cope with increased rainfall intensity and runoff. Implement green infrastructure solutions, such as rain gardens and permeable pavements, to reduce flooding.
Est. cost: High
Develop a community heatwave plan
ImmediateCreate a plan to protect vulnerable populations during heatwaves. This includes establishing cooling centers, providing outreach services, and educating residents about heat safety.
Est. cost: Low
Protect coastal areas
Long-termImplement measures to protect coastal areas from sea level rise and storm surges. This includes building seawalls, restoring coastal vegetation, and relocating infrastructure away from vulnerable areas.
Est. cost: Very High

Frequently Asked Questions
How hot does Wembley get in summer?
Wembley in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Wembley. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Wembley?
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 Wembley 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 Wembley and the performance of your building envelope.
What heat mitigation measures work best in Wembley?
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 share of Wembley is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 8.9% of Wembley in high-risk zones for bushfire, with a further 78.3% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
