Check the live forecast above before heading out, as Perth’s Mediterranean climate means summer heat can spike quickly and winter mornings can be cool, with coastal breezes often moderating peak temperatures.
What is Perth’s weather like year round?
Perth enjoys a classic Mediterranean climate—hot, dry summers and mild, wet winters. Average summer highs hover around 30–32°C during January and February, while winter (June–August) highs sit near 18–20°C, with overnight lows occasionally dipping to 8–10°C. Rainfall is heavily concentrated in the cooler months, with July typically being the wettest.
When is the best time to visit Perth?
For outdoor activities, March–April and October–November offer the most comfortable conditions: warm days, lower humidity, and less chance of extreme heat or heavy rain. Summer beach weather is reliable from December to February, but be prepared for occasional heatwaves pushing above 40°C. Winter is mild and green, ideal for exploring the Swan Valley or the city’s parks.
Does Perth get much rain?
Not compared to eastern Australia. Perth receives about 800–900 mm of rain annually, mostly between May and September. Summer months are typically dry, with only occasional thunderstorms or a rare tropical moisture surge.
What is the hottest month?
February is historically the hottest, with average highs just above 32°C, though January can see more extreme heatwaves. The warmest days often come when easterly winds blow desert air over the city.
Is Perth windy often?
Yes, especially in summer when the Fremantle Doctor (an afternoon sea breeze) regularly cools the coastal strip. Winter sees milder winds from the north-west, often ahead of cold fronts that bring rain.
