Heat Risk Analysis
Ourimbah in New South Wales faces location-specific 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 Ourimbah 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 can pose a significant health risk to vulnerable residents.
Get an address-level heat risk assessment from ClimateNest for Ourimbah including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Ourimbah. An address-level check is what tells you about a specific property before you buy, sell or insure it.
Local Hazard Evidence
Historical Events
A prolonged heatwave affected the Central Coast, with temperatures soaring above 40 degrees Celsius. This put a strain on the electricity grid and caused health problems for vulnerable residents.

Frequently Asked Questions
How hot does Ourimbah get in summer?
Ourimbah in New South Wales experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Ourimbah. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Ourimbah?
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 Ourimbah 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 Ourimbah and the performance of your building envelope.
What heat mitigation measures work best in Ourimbah?
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.
