Heat Risk Analysis
East 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 East 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.
Plan ahead for heatwaves and stay hydrated.

Frequently Asked Questions
How hot does East Hills get in summer?
East Hills in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near East Hills. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in East 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 East 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 East Hills and the performance of your building envelope.
What heat mitigation measures work best in East 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 are the main climate risks in East Hills?
ClimateNest's suburb model rates East Hills'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 East Hills.
What share of East Hills is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 14.4% of East Hills in high-risk zones for bushfire, with a further 56.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
