Heat Risk Analysis
Macquarie Hills 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 Macquarie Hills 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.
Elderly and vulnerable residents are particularly at risk during heatwaves.
Get an address-level heat risk assessment from ClimateNest for Macquarie Hills including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Macquarie Hills (postcode 2285) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are surface flood (11.5% of land in high-risk zones), bushfire (11.5% of land in high-risk zones), riverine flood (6.3% of land in high-risk zones). Exposure is not uniform across Macquarie Hills — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
How hot does Macquarie Hills get in summer?
Macquarie Hills in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Macquarie Hills. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Macquarie Hills?
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 Macquarie Hills 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 Macquarie Hills and the performance of your building envelope.
What heat mitigation measures work best in Macquarie Hills?
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 share of Macquarie Hills is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 11.5% of Macquarie Hills in high-risk zones for surface flood, with a further 67.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
