What’s the weather like in Kalamunda today?
Kalamunda’s weather today depends on the time of year, but the live forecast above tells you exactly what’s happening now. Being in the Perth Hills, Kalamunda often feels a few degrees cooler than the city centre, with afternoon sea breezes arriving later than they do on the coast. You’ll notice more cloud and slightly higher rainfall here compared to Perth’s coastal suburbs, so it’s always wise to layer up.
How does Kalamunda’s weather compare to Perth?
Kalamunda sits about 300 metres above sea level, so it’s typically 1–3°C cooler than Perth city, especially on summer afternoons and winter mornings. This elevation also means fog and frost are more common in winter, while summer thunderstorms can develop more readily over the hills. For broader conditions across the region, check our Perth weather page.
Is Kalamunda weather different from Lesmurdie weather?
Yes, slightly. Lesmurdie is just a few kilometres east of Kalamunda and sits at a similar elevation, so conditions are very similar — but Lesmurdie can be a touch cooler and windier as it’s closer to the escarpment edge.
Where can I find Kalamunda weather hourly?
For hourly details, the live forecast above shows the next few hours. For a full breakdown, the Bureau of Meteorology’s website or our Australia weather hub can give you hour-by-hour temperature, wind and rain data.
Is the Kalamunda weather radar useful?
Yes, the Kalamunda radar (Serpentine radar) is excellent for tracking rain moving in from the west or south-west, which is the most common direction for winter fronts. It helps you see showers approaching the hills 30–60 minutes ahead.
