Heat Risk Analysis

Coomba Bay 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 Coomba 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.

CSIRO climate projections indicate that under a high-emissions scenario, many parts of New South Wales could experience a doubling in the number of days over 35 °C by 2050. For Coomba Bay, this means cooling costs and occupant comfort will become increasingly important considerations.

Get an address-level heat risk assessment from ClimateNest for Coomba Bay including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.

Heat risk in Coomba Bay is tied to the broader Coastal NSW climate, and the number of days above 35°C is expected to grow through 2050 - a factor that affects cooling costs, garden viability and property desirability.

Coomba Bay located in Coastal NSW (postcode 2428), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $925,000, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Coomba Bay.

Across the six hazard axes ClimateNest models, the dominant climate risk for Coomba Bay in this type is extreme heat. Insurance signals for the suburb point to premiums rising moderately (+30% by 2030). The actual risk of any single home can only be confirmed with an address-level report.

Is extreme heat increasing in Coomba 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 New South Wales. Continued warming is likely through 2050 under all emissions scenarios.

How does heat affect energy costs for Coomba 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 Coomba Bay and the performance of your building envelope.

What heat mitigation measures work best in Coomba 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.
