Cyclone & Severe Weather Risk Reports for Australian Properties

Cyclones are moving south. Warmer oceans mean tropical cyclones can form and survive at latitudes they rarely reached before. Australia's building standards, however, still classify cyclone regions using historical wind data, with only a small allowance for climate change. That leaves an uncomfortable question for property owners along the east and west coasts: is your building designed for the storms of the past, or for the storms of its lifetime?

Our severe weather assessment answers that question from three angles: cyclone exposure, severe storm trends, and severe heat. It is the forward-looking chapter of every Property Resilience Report, alongside flood and bushfire assessments, for any address in Australia.

Three Severe Weather Risks, Assessed Separately

Cyclones

Could cyclones threaten this property, now or within the life of the building?

Cyclones need warm ocean water to form and survive, typically above 26.5 °C. Using current climate models, we assess the historical and projected sea surface temperatures near your property: will nearby waters warm enough to sustain cyclones that could not previously reach your latitude? We combine this with the property's distance from the coast. The first 50 kilometres inland carry the highest exposure, because cyclones weaken quickly over land. Then we add a third factor most assessments skip entirely: whether the structural wind requirements for your area under AS 1170 still offer adequate protection if cyclone conditions extend further south. A region built to non-cyclonic standards that faces future cyclone exposure scores higher risk than one that is already built for it.

Severe Storms

Are damaging storms becoming more likely where you are?

Warmer air holds more moisture and more energy. Storm severity is projected to increase across much of Australia, but not evenly. We assess projected changes in rainfall intensity using design rainfall data and climate adjustment factors, thunderstorm frequency based on national lightning detection records, and hail risk drawing on the latest Australian hail modelling research. Hail alone is among the most expensive natural hazards for Australian insurers. Knowing whether your area trends toward more frequent or larger hail is directly relevant to your future premiums and maintenance costs.

Severe Heat

How hot will it get, and how often?

Heat is the quiet risk. It does not destroy a house in an afternoon, but it shapes what a property costs to run and how liveable it is. We assess three indicators for your location: the overall projected temperature increase, the number of months with mean temperatures above 25 °C (when heat starts restricting outdoor activity), and the number of months above 30 °C (when sustained heat becomes a genuine health stress). If the heat picture is concerning, the report points to the most effective responses.

What You Receive

Each severe weather assessment includes individual risk scores for cyclones, storms and heat, presented on clear risk gauges with plain-language explanations. You also receive sea surface temperature maps and projections for your coastline, historical and projected temperature charts for your area, an assessment of your region's wind classification under current building standards, and practical guidance matched to your results.

We are also honest about uncertainty. Some climate projections, such as future rainfall intensity, carry wide ranges, and our report says so plainly rather than dressing estimates up as certainties.

Flood and Bushfire Risk Included

Severe weather is one part of the picture. Every Property Resilience Report also assesses flood risk and bushfire risk for your address in the same depth.

Who Uses Our Severe Weather Risk Reports
  • Homebuyers on the east and west coasts, particularly in south-east Queensland and northern NSW, where the southward drift of cyclone risk meets some of Australia's fastest-growing property markets.
  • Owners of older homes built to wind standards that predate current knowledge, weighing up structural upgrades.
  • Buyers comparing regions or towns, for whom the heat assessment doubles as a liveability and running-cost check.
  • Building and property professionals who want an independent, evidence-based risk assessment as an input to their own advice.

Frequently Asked Questions
My area isn't classified as a cyclone region. Doesn't that settle it?

Not necessarily, and this is exactly what our cyclone score is designed to catch. Australia's wind region classifications are based on historical data, and climate change is only reflected through a small safety factor applied in some regions. Ocean warming is extending the range where cyclones can survive further south. Our assessment flags locations where current building requirements and projected future conditions are drifting apart.
Does the report predict when a cyclone or storm will hit?

No. Nobody can predict individual weather events years in advance. What we assess is exposure and trend: how conditions at your location compare historically, and which direction the risk is moving under climate projections. Results are expressed as risk ratings from very low to very high, not forecasts or guarantees.
How reliable are climate projections?

It varies by hazard, and we tell you where the confidence is high and where it is not. Temperature projections are robust. Sea surface temperature trends are well established. Future rainfall intensity and wind extremes carry wider uncertainty, and our report says so explicitly. We would rather give you an honest range than false precision.
Why is heat included in a property risk report?

Because sustained heat affects a property's liveability, its cooling costs, and the health of the people in it. It is also one of the most certain consequences of a warming climate. Heat rarely makes headlines the way cyclones do, but for many Australian locations it will be the most noticeable change over a building's lifetime. It is also one of the most fixable risks: insulation and shading upgrades deliver measurable results.
How quickly will I receive my report?

Standard delivery is 3 business days. If you are on a deadline, the express option will deliver your report within 24 hours.
Can I get a report for any address in Australia?

Yes. Our data sources (Geoscience Australia elevation models, Bureau of Meteorology records and national climate projections) and models cover the entire country.
We rely on the street address to pinpoint the exact location. If your building is on a very large property or within a new development, we'd recommend contacting us before we issue a report. That way we can make sure to assess the correct location.
