Koondoola’s weather today, as shown in the live forecast above, is typical for this time of year in Perth’s northern suburbs — expect a mix of morning cloud and afternoon sea breezes, with temperatures feeling much the same as the surrounding coastal plain.
What makes Koondoola’s weather different to central Perth?
Koondoola sits about 15 kilometres north of the Perth CBD, on the Swan Coastal Plain. Its location means it often catches the afternoon sea breeze (the “Fremantle Doctor”) a little later and weaker than coastal suburbs, but it can be a degree or two warmer before that breeze arrives. The sandy soils here also heat and cool quickly, so overnight lows can drop faster than in built-up city areas.
When is the best time to plan outdoor activities?
The live forecast above gives your best guide, but in general, Koondoola’s mornings tend to be calmer and less windy than afternoons. Thunderstorms are most likely in late spring and summer, typically developing inland in the late afternoon. For gardening or walks, aim for mid-morning — before the seabreeze picks up — or check the radar on the Bureau’s site.
Why does Koondoola feel warmer than the coast?
Because it’s further inland, the cooling sea breeze arrives later and weaker. On a hot summer day, it can feel 3–5°C warmer here than at beaches like Hillarys until the breeze finally pushes through.
Does Koondoola get frost in winter?
Yes, occasionally. On clear winter nights with light winds, temperatures can drop to 2–4°C in the early morning, creating light frost in low-lying parts of the suburb. This is less common than in the Swan Valley further east.
Is the rain different from central Perth?
Generally no — Koondoola gets similar seasonal rainfall totals to the northern suburbs (around 750–800 mm annually). Most rain falls between May and September from cold fronts, with summer storms being more localised and patchy.
