To help keep Australians safe, our fire weather services include:
Fire agencies in each state and territory are responsible for total fire bans. Check with your state or territory fire agency for any fire bans or other restrictions.
We issue fire weather warnings:
We update warnings regularly and reissue them as needed.
See Current warnings.
Fire danger ratings indicate how difficult it will be to control or suppress a fire. The rating is set by state and territory fire agencies, based on weather and other conditions. This includes:
Four levels of fire danger ratings communicate the level of bushfire risk – from moderate to catastrophic. 'No rating' may be shown when there is low risk, during the fire season.
Learn more about the Australian Fire Danger Rating System on the Australasian Fire and Emergency Service Authorities Council (AFAC) website.
Australian fire danger rating scale
For the latest fire danger ratings:
The fire behaviour index (FBI) is a scale of potential fire behaviour. It ranges from zero to 100-plus.
Fire agencies use the FBI to inform decisions about the fire danger rating for a district, along with information about other conditions.
We use mathematical models to predict potential fire behaviour characteristics, based on weather and fuel information. For example, the models can predict:
There are models for 8 vegetation types:
The models calculate the FBI number for a district based on predicted fire intensity or rate of spread. This informs the fire danger rating for that district.
Within the index, there are number ranges (categories). Each category aligns to a level of the fire danger rating scale. See 'FBI categories for fire danger ratings' on this page.
The FBI number for a district will be in one of these categories. This indicates the fire danger rating for that district.
It also means the fire danger rating reflects expected fire behaviour. This supports organisations making operational decisions about, for example:
|Index number range (category)||Fire danger rating|
|0 to 11||No rating|
|12 to 23||Moderate|
|24 to 49||High|
|50 to 99||Extreme|
The Bureau of Meteorology publishes a Fire Weather Service Level Specification that describes the available fire weather services we provide and when each product is issued. The SLS is available here.
