Perth’s Mediterranean climate delivers hot, dry summers and mild, wet winters. As the live forecast above shows, today’s conditions reflect this pattern. Positioned on Australia’s western coast, Perth experiences some of the most consistent summer weather in the country.
What defines Perth’s weather pattern?
Perth sits on the Swan River coastal plain with the Indian Ocean to the west, creating a sharp seasonal divide. Summer brings sustained heat with average January maxima around 31°C, while winter is cooler and wetter with July averages near 18°C. The Fremantle Doctor, an afternoon sea breeze from the Indian Ocean, provides natural cooling on summer afternoons, typically dropping temperatures by 5–10°C.

How useful are extended forecasts for Perth?
For planning, the weather perth 14 days outlook and perth weather 10 days projections give a solid sense of trends, though day-to-day accuracy declines beyond a week. The 28 day weather forecast perth is useful for spotting long-term patterns but less reliable for specific conditions. For the most precise reading, bom perth weather is the official source, particularly when checking weather in perth tomorrow or perth weather 15 days ahead. When looking at perth weather monthly, seasonal averages are more dependable than individual predictions. During summer and autumn, the perth weather cyclone outlook becomes relevant if tropical systems develop off the coast, and we track these on our severe weather warning page.
What is the Fremantle Doctor?
The Fremantle Doctor is a cooling sea breeze that arrives from the Indian Ocean on summer afternoons, typically between midday and 3 pm. It reliably drops temperatures by 5–10°C and is a defining feature of Perth’s summer climate.
Does Perth get cyclones?
Perth rarely experiences direct cyclone hits, but ex-tropical cyclones can bring heavy rain and strong winds. The perth weather cyclone updates during summer and autumn are worth monitoring if a system is active off the coast.
Which month is hottest in Perth?
February is typically the hottest month, with average maxima around 31.7°C, closely followed by January. Both months see frequent days above 35°C, though the afternoon sea breeze usually brings relief.
