Fire Danger Index

Daily Index Values

The FFDI and GFDI indices are initially calculated at 10:35 am AEST each day (11:35 am AEDT) by FWI Calc using Truganina Weather data. The indices are recalculated at regular intervals during the day as the weather conditions change.

Grassland Curing

During the fire season, a network of CFA volunteers provide weekly assessments of the amount of dry and dead grass, also known as grassland curing. The level of curing is an important factor in predicting fire behaviour and has a dramatic effect on the GFDI.
