Heat Risk Analysis
Erina Heights 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 Erina Heights 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.
Average maximum temperatures in January are increasing, leading to more frequent heat stress events.

Frequently Asked Questions
How hot does Erina Heights get in summer?
Erina Heights in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Erina Heights. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Erina Heights?
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 Erina Heights 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 Erina Heights and the performance of your building envelope.
What heat mitigation measures work best in Erina Heights?
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 Erina Heights?
ClimateNest's suburb model rates Erina Heights's dominant climate risk as extreme heat at 5/10 on a 0–10 index, followed by damaging wind (5/10) and severe storm (5/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Erina Heights.
What share of Erina Heights is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 14.2% of Erina Heights in high-risk zones for bushfire, with a further 77.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
