Perth’s cold weather rain this week is being driven by a sluggish trough sitting off the coast, with the live forecast above showing persistent showers and a top around 17°C today. The rainband will linger into Thursday before clearing to a cooler, showery weekend.
How long will the cold rain last in Perth?
The live forecast above indicates the main rainband will clear by Friday morning, but a brisk westerly flow will keep isolated showers and a cool, blustery feel through the weekend. The seabreeze perth typically moderates coastal temps, but today it’s barely kicking in — expect a raw day along the river and beach suburbs.
What should I expect for the next week?
Looking at the weather perth 14 days outlook, the cold snap eases early next week as a stronger ridge builds. The bom weather perth guidance suggests the worst of the rain is confined to the next 48 hours, with a gradual return to the low 20s by Tuesday. For the weekend, check the weather perth 7 days forecast — a mix of sun and showers, but certainly not the persistent drizzle of today.
Will it snow on the hills around Perth?
No — the freezing level stays above 1200 metres, so any rain on the Darling Scarp will be just cold showers. For snow you’d need a much stronger cold front, which is unlikely this week.
Is the rain enough to ease water restrictions?
Not significantly. This single rain event will wet the ground and top up garden tanks, but Perth’s broader rainfall deficit persists. The weather in perth tomorrow shows only patchy falls.
What’s the best time to avoid the rain today?
The bom perth 7 day forecast shows a brief drier window mid-morning, but the heaviest rain arrives mid-afternoon. If you need to head out, aim for before 10am — the seabreeze perth will strengthen after lunch.
