Dundas is looking at a mostly fine day, with the live forecast above showing conditions typical of late spring in Sydney’s north-west suburbs. The area, nestled between Parramatta and the hills of the Dundas Valley, often sees a few extra degrees of warmth compared to the coast.
What’s driving the weather in Dundas today?
The pattern is being shaped by a weak trough sitting over the central ranges, keeping a light north-easterly breeze flowing across the Cumberland Plain. For Dundas, this means a mix of sun and cloud, with the chance of a brief afternoon shower if the seabreeze pushes inland far enough. Humidity is moderate, making it feel a touch stuffier than in nearby Blacktown or Parramatta, but nothing out of the ordinary for November. The Sydney weather outlook suggests this settled spell will hold for a couple more days before a change arrives from the south.
How does Dundas compare to nearby suburbs?
Dundas sits inland enough to escape the direct cooling of the ocean, so it often runs 2–3°C warmer than the coast on a sunny spring day. Compared to Parramatta weather just a few kilometres south, Dundas can be a fraction cooler in the morning due to its position in the valley. For a more granular look, the dundas weather hourly forecast is useful for planning outdoor activities, as the afternoon seabreeze can arrive later here than in eastern suburbs.
Does Dundas ever get severe storms?
Yes, like much of western Sydney, Dundas can see severe thunderstorms in spring and summer, often tracking from the Blue Mountains. The Severe Weather Warning page is the best place to check for watches.
Is the dundas weather radar different to Sydney’s?
There is no dedicated radar for Dundas itself. The nearest useful radar is Terrey Hills, which covers the whole Sydney basin and gives good detail for the Dundas Valley area.
Why is Dundas often warmer than the city?
Dundas sits on the Cumberland Plain, away from the moderating influence of the ocean. Inland suburbs like Dundas and Blacktown weather regularly record higher maximums than the CBD, especially on clear, calm nights.
