As shown in the live forecast above, Cowaramup’s conditions are mild and coastal. This small town in the Margaret River wine region enjoys a Mediterranean climate with warm summers and wet winters. The ocean breeze keeps temperatures moderate, but afternoon sea breezes often pick up.
What’s the typical weather pattern for Cowaramup?
Cowaramup sits about 10 kilometres inland from the coast, so its daily weather is influenced by the Indian Ocean. Summer days (December–February) are warm and mostly dry, with clear skies and light easterly mornings that shift to a sea breeze by lunchtime. Winter (June–August) brings persistent westerly winds and rain bands from the south-west. Frost is rare, but winter mornings can feel cold because of the damp air. The region’s weather changes quickly when a cold front passes, so checking the live forecast above or the full cowaramup weather 14 days outlook helps with planning.
How does the coastal location affect humidity and wind?
Humidity stays moderate year-round, rarely feeling oppressive except during occasional pre-frontal northerlies. Wind is the key factor: summer afternoons bring a strong sea breeze, often gusting to 30–40 km/h, which makes conditions feel cooler. In winter, the wind shifts to the west and south-west, with stronger gusts during cold fronts. If you need detailed timing, the cowaramup weather hourly forecast breaks down those wind and temperature changes.

When is the best time to visit Cowaramup for fine weather?
Late spring (November) and early autumn (March–April) offer the most stable conditions: low humidity, light winds, and daytime temperatures around 22–26°C. December and January are hotter but still pleasant if you avoid the hottest afternoons.
Does Cowaramup get much rain?
Yes – annual rainfall averages about 1,100 mm, with the wettest months between May and August. Showers often arrive from the west in short, heavy bursts. The live forecast above will show any approaching rain bands.
