Waikiki weather in Western Australia is typically hot and dry in summer, with a mild, wetter winter. The live forecast above shows today’s conditions, so use that as your immediate guide before heading out.
What defines Waikiki’s climate?
Waikiki, a coastal suburb of Rockingham, sits in a Mediterranean climate zone. Summers (December–February) bring average highs around 29–32°C, with low humidity and clear skies. Winters (June–August) are cooler, with highs near 17–19°C and most of the annual rainfall concentrated in these months. Sea breezes often moderate the heat in summer, making afternoons more comfortable.
How does the live forecast help you plan?
The live forecast above gives you the current temperature, wind speed, and chance of rain. For Waikiki, the key detail is the afternoon sea breeze: if the forecast shows a southwesterly wind picking up after midday, expect a rapid drop in temperature near the coast. Check the UV index too—summer days often reach extreme levels, so sun protection is essential between 10am and 4pm.
Does Waikiki get cyclones or severe storms?
Cyclones are very rare this far south, but summer thunderstorms can bring heavy downpours and gusty winds. Check our severe weather warning page if a warning is current for the Perth region.
What’s the water temperature like for swimming?
Sea surface temperatures in Waikiki range from about 19°C in winter to 23°C in late summer. The live forecast above includes water temperature if available—otherwise, expect a refreshing but not cold swim year-round.
Is Waikiki’s weather similar to Perth’s?
Yes, very similar, though Waikiki is slightly cooler in summer due to its coastal position. For broader conditions, see our Perth weather page or the Australia weather hub.
