Heat Risk Analysis
Terry Hie Hie 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 Terry Hie Hie 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 area experiences hot summers, with temperatures frequently exceeding 35°C.
Get an address-level heat risk assessment from ClimateNest for Terry Hie Hie including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Terry Hie Hie (postcode 2400) 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 riverine flood (14.4% of land in high-risk zones), surface flood (12% of land in high-risk zones), bushfire (8.9% of land in high-risk zones). Exposure is not uniform across Terry Hie Hie — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Is extreme heat increasing in Terry Hie Hie?
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 Terry Hie Hie 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 Terry Hie Hie and the performance of your building envelope.
What heat mitigation measures work best in Terry Hie Hie?
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 Terry Hie Hie is exposed to high riverine flood risk?
ClimateNest's hazard overlay maps 14.4% of Terry Hie Hie in high-risk zones for riverine flood, with a further 60.8% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
