Perth’s weather is defined by hot, dry summers and cool, wet winters. The live forecast above shows today’s conditions, typical of a Mediterranean climate that sees more than 3,000 hours of sunshine annually.
What is the typical seasonal pattern for Perth weather?
Perth experiences distinct seasons. Summer (December–February) brings average highs around 30–33°C, often with easterly morning winds and a cooling afternoon sea breeze known as the “Fremantle Doctor.” Winter (June–August) is mild and damp, averaging 18–19°C, with most of the city’s annual rainfall falling in this period. Spring and autumn are transitional, offering warm days and cooler nights.
- Summer: Hot, dry, with occasional heatwaves. The bom perth weather service frequently issues fire danger warnings during this time.
- Winter: Cool and cloudy, with persistent fronts from the Southern Ocean. A 28 day weather forecast perth often shows a split between dry spells and rainy weeks.
- Spring: Most stable season; ideal for outdoor plans. Check a perth weather 10 days outlook for fine conditions.
- Autumn: Warmer days linger, but nights cool quickly.
What should I know about extended forecasts and severe weather?
For planning ahead, a perth weather 14 days forecast gives a general trend but becomes less reliable beyond a week. The bureau also offers a perth weather 15 days outlook for long-range patterns, though daily confidence drops. If you need monthly planning, a perth weather monthly summary from the BOM is more useful than an extended single forecast.
- Cyclones: While rare, tropical lows can drift south, bringing heavy rain and wind. Stay alert via perth weather cyclone updates from the BOM.
- Warnings: Severe storms and heatwaves are the main risks. Check our severe weather warning page for current alerts.
- Tomorrow: For weather in perth tomorrow, the live forecast is your best guide; morning sea breezes can shift conditions quickly.
What is the warmest month in Perth?
February is typically the warmest, with average maximum temperatures around 31.5°C. However, January can also peak higher during heatwaves. The cooling sea breeze usually arrives by early afternoon.
How reliable is a 28 day weather forecast perth?
A 28-day forecast offers only a broad climate trend, not specific daily weather. It is useful for seeing if a dry or wet pattern is likely, but for accurate planning, rely on the 7-day forecast provided by the Bureau of Meteorology.
Does Perth ever get cold in summer?
Very rarely. Summer overnight lows generally stay above 15°C. The occasional cold front can drop daytime temperatures to the low 20s°C, but this is short-lived and considered a cool relief rather than cold.
