The GRW can be walked at any time of the year, though high summer of mid-winter are best to be avoided. It all depends on your level of experience and motivation for walking the track.
Summer: Particularly January and February can be very hot and dry on track. There are significant fire danger risks through summer and it is best to avoid walking in bushland on days of Total Fire Ban. If walking during summer or any warm period you will need to carry extra water and keep alert to fire conditions. Best to start early and rest during the heat of the day.
Autumn & Spring: The shoulder seasons are a great time to walk, the days are long still but normally not too hot or cold. Spring will present more wildflowers. Autumn is typically a bit warmer than Spring.
Winter: Expect nighttime temperatures to drop below zero – day time temperatures can also drop below zero. This leads to icy conditions and means walkers will require extra warm clothing.
Always check and heed the weather forecast before setting off on your walk.
