Heat Risk Analysis
St Fillans 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 Fillans 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.
Urban heat island effect may amplify temperatures in built-up areas.
Get an address-level heat risk assessment from ClimateNest for St Fillans including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
St Fillans (postcode 2850) 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 (9.1% of land in high-risk zones), surface flood (7.7% of land in high-risk zones), extreme wind (6.8% of land in high-risk zones). Exposure is not uniform across St Fillans — 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 Fillans get in summer?
St Fillans in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near St Fillans. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in St Fillans?
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 Fillans 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 Fillans and the performance of your building envelope.
What heat mitigation measures work best in St Fillans?
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 Fillans is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 9.1% of St Fillans in high-risk zones for bushfire, with a further 75.9% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
