Swanbourne’s weather is shaped by its coastal Perth location, bringing mild, wet winters and hot, dry summers. The live forecast above shows today’s conditions, but expect a sea breeze most afternoons to cool things down.
What is the typical seasonal pattern?
Summer (December–February) sees average highs around 30°C, often hotter inland before the afternoon “Fremantle Doctor” sea breeze arrives. Winters (June–August) are cool and damp, with average highs of 18°C and most of the yearly rain falling then. Spring and autumn are short, mild transitional seasons with occasional thunderstorms.

Does Swanbourne get much wind?
Yes, especially in summer afternoons. The coastal location means a reliable sea breeze (often 20–30 km/h) kicks in by mid-afternoon, which can make beach conditions gusty but pleasant.
Is the water warm enough to swim in winter?
Winter sea temperatures drop to about 17–19°C, which feels cool but is swimmable with a wetsuit. Summer water temps reach 22–24°C, ideal for long swims.
How accurate are 14-day forecasts for Swanbourne?
