Heat Risk Analysis
Coral Bay in Western Australia 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 Coral Bay 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 January maximum temperature is increasing, leading to more frequent heat stress events.
Get an address-level heat risk assessment from ClimateNest for Coral Bay including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
Climate projections show heat risk in Coral Bay is tied to the broader Coastal WA climate. The suburb scores 5 on the 0–10 heat index, with the number of days above 35°C expected to grow through 2050 — a factor that affects cooling costs, garden viability and property desirability.
Coral Bay located in Coastal WA (postcode 6701), is a Western Australia suburb tracked by ClimateNest. The suburb's median property value is $575,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Coral Bay.
Across the six hazard axes ClimateNest models, the dominant climate risk in Coral Bay is extreme heat (score 5/10), with moderate exposure. Insurance signals for the suburb point to premiums rising moderately (+25% by 2030). These suburb-level signals help prioritise which properties need the closest look — the actual risk of any single home can only be confirmed with an address-level report.
Whether you are buying, selling or renovating in Coral Bay, extreme heat is the hazard to weigh first. Local council planning controls, state hazard mapping and lender climate policies each reference this kind of suburb-level signal, and property decisions in Coral Bay are increasingly made with an address-level climate report in hand.

Frequently Asked Questions
How hot does Coral Bay get in summer?
Coral Bay in Western Australia experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Coral Bay. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Coral Bay?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for Western Australia. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Coral Bay 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 Coral Bay and the performance of your building envelope.
What heat mitigation measures work best in Coral Bay?
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 Coral Bay?
ClimateNest's suburb model rates Coral Bay's dominant climate risk as extreme heat at 5/10 on a 0–10 index, followed by damaging wind (5/10) and bushfire (4/10). These are suburb-level averages — an address-level report is needed to confirm the risk of a specific property in Coral Bay.
What share of Coral Bay is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 22% of Coral Bay in high-risk zones for bushfire, with a further 68.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
