Heat Risk Analysis
Crawley in Western Australia experiences seasonal temperature variations typical of the region. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since national records began in 1910, with the frequency of extreme heat days also rising across most of the country.
The urban heat island (UHI) effect can make built-up areas of Crawley several degrees warmer than surrounding rural areas, particularly during summer nights. Factors such as dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress.
CSIRO climate projections indicate that under a high-emissions scenario, many parts of Australia could experience a doubling in the number of days over 35 °C by 2050. For suburbs like Crawley, this means cooling costs, occupant comfort, and building durability will become increasingly relevant considerations for property owners and buyers.
Use ClimateNest to get a property-specific heat risk report for Crawley including projected cooling costs, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Climate projections show heat risk in Crawley 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.
Crawley located in Greater Perth (postcode 6009), 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 Crawley.
Across the six hazard axes ClimateNest models, the dominant climate risk in Crawley is extreme heat (score 6/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+20% by 2030). These suburb-level signals help prioritise which properties need the closest look — the actual risk of any single home can only be confirmed with an address-level report.
Whether you are buying, selling or renovating in Crawley, extreme heat is the hazard to weigh first. Local council planning controls, state hazard mapping and lender climate policies each reference this kind of suburb-level signal, and property decisions in Crawley are increasingly made with an address-level climate report in hand.

Frequently Asked Questions
How hot does Crawley get in summer?
Crawley in Western Australia experiences summer temperatures consistent with the regional climate. For specific temperature records, BOM publishes historical climate data for weather stations near Crawley. Get a property-specific heat exposure assessment from ClimateNest.
Is extreme heat increasing in Crawley?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with climate projections for regions including Western Australia. CSIRO data indicates continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Crawley properties?
Higher temperatures increase cooling demand, which raises electricity costs for properties without efficient insulation or passive design features. ClimateNest provides energy cost projections based on your property's specific exposure to extreme heat days in Crawley.
What heat mitigation measures work best in Crawley?
Effective heat mitigation includes light-coloured roofing (cool roofs), ceiling and wall insulation, double-glazed windows, eaves and external shading, cross-ventilation design, and increasing tree canopy and vegetation around the property. These measures reduce indoor temperatures and cooling costs.
Which suburbs near Crawley are cooler?
Temperature varies across suburbs due to factors like elevation, distance from the coast, vegetation cover, and urban density. Suburbs with more tree canopy, higher elevation, or coastal breezes tend to experience lower extreme heat. ClimateNest compares heat risk across Western Australia suburbs.
What are the main climate risks in Crawley?
ClimateNest's suburb model rates Crawley'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 Crawley.
What share of Crawley is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 11.3% of Crawley in high-risk zones for surface flood, with a further 69.1% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
