Treeby’s current live reading is shown in the forecast above, with the day’s high likely to reach the low-to-mid 30s Celsius under mostly sunny skies. This means a hot, stable afternoon for the suburb, typical of a Perth summer day with light sea breezes developing later.
What does the rest of the week look like for Treeby?
Expect a sequence of warm to hot days through the coming week, with overnight lows hovering around 16–19°C. A weak trough may brush the coast mid-week, producing a slight chance of a late shower but no significant rainfall is forecast. Winds will shift from easterly in the mornings to southwesterly by the afternoon, keeping humidity moderate.
How does Treeby’s weather compare to wider Perth?
Treeby sits in Perth’s southern corridor, so it often registers 1–2°C warmer than the city centre under clear skies due to inland heating. The pattern above mirrors conditions across the broader Perth weather region, though coastal suburbs may see a sea breeze arrive an hour or two earlier. For context, the same synoptic setup can produce cooler conditions in Melbourne weather due to a different latitude and frontal activity.
Is Treeby prone to severe storms?
Severe thunderstorms are rare in Treeby compared to eastern states, but occasional summer storms do develop—especially when a trough moves inland. For alerts, refer to our severe weather warning page for real-time updates.

Does Treeby get much rainfall annually?
Treeby receives about 730 millimetres of rain per year, with most falling between May and August. Summer months are typically dry, consistent with the Australia weather patterns experienced across southwest Western Australia.
