Australian Bushfire Weather Guide
Understanding fire danger ratings, conditions, and safety measures
Overview
Bushfire weather refers to atmospheric conditions that increase the likelihood and intensity of bushfires. Australia experiences some of the most severe bushfire conditions in the world, with the 2019-2020 Black Summer fires burning over 24 million hectares and affecting three billion animals.
The Bureau of Meteorology issues Fire Weather Warnings when dangerous fire weather conditions are expected. These warnings are coordinated with state fire agencies who issue Fire Danger Ratings (FDR) under the Australian Fire Danger Rating System (AFDRS) introduced in September 2022.
Understanding bushfire weather is critical for all Australians, particularly those in rural and peri-urban areas. The fire season is extending due to climate change, with some regions now experiencing year-round fire risk.
Causes & Contributing Factors
- High temperatures (typically above 35°C)
- Low relative humidity (below 20%)
- Strong, gusty winds (particularly wind changes)
- Extended dry periods reducing fuel moisture
- Lightning strikes during dry thunderstorms
- Climate change increasing frequency of extreme fire weather days
Safety Tips
Have a Bushfire Survival Plan
Decide whether you will leave early or stay and defend. If leaving, know your trigger to go and where you will go.
Prepare Your Property
Clear gutters, maintain a defendable space, have firefighting equipment ready, and ensure adequate water supply.
Monitor Conditions
Check Fire Danger Ratings daily, download emergency apps, and tune into ABC Local Radio for updates.
Leave Early on High-Risk Days
On Catastrophic fire danger days, leaving early is the only safe option. No home is designed to withstand Catastrophic conditions.
Know the Fire Danger Ratings
Understand what each rating means: Moderate, High, Extreme, and Catastrophic (Code Red in some states).
Protect Your Health
Smoke from bushfires can travel hundreds of kilometres. Stay indoors, use air purifiers, and wear P2 masks if outside.
