Future Heatwave Risks in New South Wales
Integrating climate analysis with NARCLiM2 and CMIP6 models to provide an evidence-based foundation for Local Government Areas.

This interactive mapping tool is a core component of the Heatwave Hub which provides an analysis of heatwave preparedness of NSW. By integrating detailed climate analysis with community-specific data, this tool provides an evidence-based foundation for Local Government Areas, Emergency Services, Government, and Health Authorities.
What is the Combined Heatwave Risk Index (CHRI)?
The Combined Heatwave Risk Index (CHRI) is a multi-dimensional metric used to quantify regional heat risk. It moves beyond simple temperature monitoring by calculating the intersection of Hazard severity, Population vulnerability, and Physical exposure. This allows decision-makers to identify not just where it is hot, but where the heat will have the most significant human and social impact.
The CHRI offers a balanced score by averaging three critical components:
Represents the potential of a heatwave to cause harm based on frequency and intensity. Data derived from historical records (1951–2022) and future projections using NARCLiM2 and CMIP6 models.
Measures susceptibility of a population to heat-related harm, including demographics (age ≥ 65 years), chronic health conditions (heart, kidney, or lung disease), and disability requiring assistance.
Accounts for the number of people physically located in areas affected by heat hazards.
