Dundas weather today, as shown in the live forecast above, is typical for this time of year in Sydney’s north-west suburbs, with conditions influenced by the nearby Parramatta River and the Cumberland Plain.
What is the typical weather pattern for Dundas?
Dundas experiences a humid subtropical climate, with warm summers and mild winters. The area is often a few degrees warmer than coastal Sydney due to its inland position, and it can be affected by the same storm systems that bring rain to Blacktown and Parramatta.
- Summer (December–February): Average highs around 28–30°C, with occasional afternoon thunderstorms and high humidity.
- Winter (June–August): Average highs near 17–18°C, with cool, clear nights and morning fog in the Dundas Valley.
- Spring and autumn are transitional, with mild days and lower rainfall than summer.
How does Dundas weather compare to nearby suburbs?
Dundas sits in the Dundas Valley, which can trap cooler air overnight, leading to lower minimums than in Parramatta or Sydney CBD. Daytime temperatures are similar to those in nearby Ermington and Rydalmere.
- Summer maximums are often 1–2°C cooler than Blacktown, due to the valley’s sheltering effect.
- Winter minimums can drop 2–3°C lower than Sydney’s coast, especially on clear nights.
- Rainfall is generally consistent with the broader Sydney region, though localised storms can vary.
