Heat Risk Analysis
St Ives 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 St Ives 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.
Heatwaves are becoming more frequent and intense in the Sydney region.

St Ives (postcode 2075) 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 bushfire (21.7% of land in high-risk zones), surface flood (8.8% of land in high-risk zones), riverine flood (6% of land in high-risk zones). Exposure is not uniform across St Ives — 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 St Ives get in summer?
St Ives in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near St Ives. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in St Ives?
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 St Ives 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 St Ives and the performance of your building envelope.
What heat mitigation measures work best in St Ives?
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 St Ives is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 21.7% of St Ives in high-risk zones for bushfire, with a further 73.3% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
