Perth Weather by Month

High Season (November to March): The best time for guaranteed sunshine with hot days, but rates peak from mid-December to late January.

Shoulder Season (September, October, April, and May): If you’re okay with taking a chance with the weather, this time will give you cheaper airfares and accommodation. However, rates will increase for the Easter and September school holidays. Spring and autumn are my favourite times of the year.

Low Season (June to August): Winter is the quietest time in Perth and offers the lowest accommodation prices. However, it can be wet and windy, leaving little to do.

Noongar Calendar

Noongar country extends from Leeman on Australia’s Coral Coast to beyond Cape Arid, near Esperance, in Australia’s southwest. The Noongar calendar includes six seasons – Birak, Bunuru, Djeran, Makuru, Djilba, and Kambarang.

Each season represents seasonal changes that occur annually, like the flowering of different plants, the hibernation of reptiles, and the moulting of swans.

As the land guides the seasons, they can be long or short and do not have set dates.
