Western Australia Weather & Climate Guide 2026

Western Australia's climate in numbers — the months that flatter it, the ones to avoid, and what to pack.

Western Australia is Australia's largest state, covering more than one-third of the continent and offering an extraordinary range of landscapes from pristine coral reefs and red outback deserts to verdant wine regions and cosmopolitan coastal cities. Home to Perth, one of the world's most isolated yet vibrant capital cities, Western Australia rewards adventurous travellers with World Heritage sites, unique wildlife, and some of the planet's most spectacular natural wonders.

Best time to visit

Recommendation

Overall Recommendation: April to October

Peak Season: June to August (WA school holidays) and December-January (Perth summer)

Shoulder Season: April-May and September-October

Avoid: December to March in northern WA (Kimberley, Pilbara, Gascoyne) due to extreme heat, cyclone risk, and wet season road closures. January-February in Perth can be very hot (40°C+ heatwaves).
