Heat Risk Analysis
Ettrema in New South Wales 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 Ettrema 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.
Ettrema experiences an average of 3 heat stress events per year, with temperatures exceeding 35°C. These events can pose a significant risk to vulnerable populations.
Get an address-level heat risk assessment from ClimateNest for Ettrema including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Heat risk in Ettrema is tied to the broader Regional NSW climate, and the number of days above 35°C is expected to grow through 2050 - a factor that affects cooling costs, garden viability and property desirability.
Ettrema located in Regional NSW (postcode 2540), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $550,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Ettrema.

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