Sydney’s mix of sun and showers this week will keep the weekend plans flexible — expect a few damp days from midweek before a drier, milder spell arrives. The live forecast above gives the day-by-day details, but a coastal trough is the main driver.
What’s behind the unsettled stretch?
A slow-moving low off the coast is pulling humid air over the harbour and beaches, triggering afternoon storms, especially Wednesday and Thursday. The 14 day weather forecast sydney suggests a gradual clearing as a high builds from the west towards Friday. For the city and surrounds — from Parramatta down to Cronulla — keep the umbrella handy for sudden downpours, but don’t expect a washout.
When does a clearer outlook return?
By Friday the trough weakens, and the weather in sydney 10 days shows a ridge settling over the coast. The weekend should offer more sun and lighter winds, with temperatures easing back to the low 20s. If you’re planning a trip to the Blue Mountains, the 21 day weather forecast sydney points to stable conditions next week.
Will the weather in sydney tomorrow be worse than today?
Tomorrow (Wednesday) sees the highest chance of showers and a possible storm. The trough is strongest then, so if you have outdoor plans, aim for the morning before the convection fires up.
Is a heatwave likely this week?
No. Even on the warmest days temperatures sit near the November average. Humidity makes it feel muggy, but the live forecast above doesn’t indicate any prolonged heat for the city or inland suburbs.
Where can I check the 30‑day outlook?
The Bureau of Meteorology issues a sydney weather forecast 30 days only as a broad trend. For a more reliable view, combine the live forecast above with the 14 day weather forecast sydney page on Southern Pulse.
