Perth Weather Today

Perth has one of the most distinctive climates of any Australian capital city — a Mediterranean climate characterised by hot, dry summers and cool, wet winters. Perth is isolated from the rest of Australia's east coast weather systems and is instead dominated by the Indian Ocean to the west and the arid interior to the north and east. It is consistently one of the sunniest cities in the world, averaging over 3,000 hours of sunshine per year.

Perth Climate — What to Expect Each Season

• Summer (December to February) — Very hot and dry. Average January maximum: 31.4°C, with regular heatwave periods pushing above 40°C. The afternoon Fremantle Doctor sea breeze is a defining feature — it typically arrives between 2pm and 4pm and can drop temperatures by 10°C or more. Rainfall is minimal in summer.
• Autumn (March to May) — Still warm but temperatures moderate gradually. The first autumn rains typically arrive in May. March can still produce hot weather.
• Winter (June to August) — Perth's wet season. Cool and wet by Perth standards — average July maximum 18.0°C, minimum 7.8°C. Significant cold fronts cross the city approximately weekly, bringing rainfall. The Wheatbelt region to the east can experience frost.
• Spring (September to October) — Mild, increasingly sunny and dry. Wildflower season across Western Australia. October sees rapid temperature increases and the return of sea breezes.
