Heat Risk Analysis
South Fremantle 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 South Fremantle 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 significantly in the coming decades.

Frequently Asked Questions
How hot does South Fremantle get in summer?
South Fremantle in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near South Fremantle. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in South Fremantle?
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 South Fremantle 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 South Fremantle and the performance of your building envelope.
What heat mitigation measures work best in South Fremantle?
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.
