Heat Risk Analysis
Cannington 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 Cannington 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 suburb experiences several days above 35°C each summer. The urban heat island effect can increase temperatures by several degrees.

Frequently Asked Questions
How hot does Cannington get in summer?
Cannington in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Cannington. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Cannington?
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 Cannington 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 Cannington and the performance of your building envelope.
What heat mitigation measures work best in Cannington?
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 Cannington?
ClimateNest's suburb model rates Cannington'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 Cannington.
What share of Cannington is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 16.8% of Cannington in high-risk zones for bushfire, with a further 78.1% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
