Heat Risk Analysis
Comerong Island in New South Wales 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 Comerong Island 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.

Frequently Asked Questions
How hot does Comerong Island get in summer?
Comerong Island in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Comerong Island. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Comerong Island?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for New South Wales. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Comerong Island 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 Comerong Island and the performance of your building envelope.
What heat mitigation measures work best in Comerong Island?
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 Comerong Island?
ClimateNest's suburb model rates Comerong Island's dominant climate risk as extreme heat at 6/10 on a 0–10 index, followed by bushfire (5/10) and damaging wind (4/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Comerong Island.
What share of Comerong Island is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 17.1% of Comerong Island in high-risk zones for bushfire, with a further 73.7% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
