If you’re heading out in Cockburn today, check the live forecast above for the immediate conditions, as the city’s coastal position means sea breezes can shift the temperature and humidity quickly through the afternoon.
What’s driving Cockburn’s weather today?
Cockburn sits on the western edge of the Perth metropolitan area, so its weather is heavily influenced by the Indian Ocean. The live forecast above reflects the balance between a morning easterly and the afternoon south-westerly “Fremantle Doctor” that often cools things down. For a broader view of the region, see our Perth weather page.
How does Cockburn’s climate compare to nearby suburbs?
Being coastal, Cockburn is typically a degree or two cooler than inland suburbs like Treeby during summer afternoons, but it can feel more humid. If you’re checking Australia weather for the area, note that cockburn weather hourly updates are useful for planning around the sea-breeze change. For comparison, Melbourne weather follows a very different pattern, driven by cold fronts rather than a daily ocean breeze.
Is Cockburn weather usually windier than Perth city?
Yes, generally. Cockburn’s open coastal exposure means the afternoon sea breeze is often stronger than in central Perth, especially from November to March. This can make it feel cooler than the temperature suggests.
How does Cockburn weather compare to Mandurah weather?
Mandurah, about 70 km south, is also coastal but often sees slightly higher humidity and a more pronounced sea breeze. Cockburn tends to be a touch warmer in winter and less humid in summer than Mandurah.
