Heat Risk Analysis
Cammeray 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 Cammeray 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.
Urban areas experience higher temperatures due to the urban heat island effect.
Get an address-level heat risk assessment from ClimateNest for Cammeray including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Climate projections show heat risk in Cammeray is tied to the broader Greater Sydney climate. The suburb scores 5 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.
Cammeray located in Greater Sydney (postcode 2062), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $1.6 million, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Cammeray.
Across the six hazard axes ClimateNest models, the dominant climate risk in Cammeray is extreme heat (score 5/10), 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 Cammeray, 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 Cammeray are increasingly made with an address-level climate report in hand.

Frequently Asked Questions
How hot does Cammeray get in summer?
Cammeray in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Cammeray. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Cammeray?
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 Cammeray 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 Cammeray and the performance of your building envelope.
What heat mitigation measures work best in Cammeray?
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 Cammeray?
ClimateNest's suburb model rates Cammeray's dominant climate risk as extreme heat at 5/10 on a 0–10 index, followed by damaging wind (4/10) and severe storm (4/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Cammeray.
What share of Cammeray is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 9.3% of Cammeray in high-risk zones for surface flood, with a further 84.9% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
