Illawong is currently experiencing mild and settled conditions, with the live forecast above showing a clear sky and light winds. This suburb in southern Sydney typically tracks a few degrees cooler than the city centre due to its proximity to the Georges River and bushland.
What is the typical weather pattern for Illawong?
Illawong sits within the Sutherland Shire, about 25 kilometres south of the Sydney CBD. Its weather mirrors much of sydney weather but with slightly lower overnight temperatures. Summer afternoons often reach the high 20s Celsius, while winter maximums hover around 16–18 °C. The area receives moderate rainfall spread across the year, with autumn and early winter being the driest months.
Where can I check Illawong weather radar and hourly details?
For illawong weather radar the Bureau of Meteorology’s Terrey Hills radar provides the best coverage. To see illawong weather hourly updates, use the BOM’s spot forecast page or a dedicated weather app. For a broader view, bankstown weather can serve as a useful reference because Bankstown Airport’s observations are only about 10 kilometres north-west and capture similar conditions.
Does Illawong ever get severe storms?
Yes, like much of the Sydney basin, Illawong can experience severe thunderstorms, especially in spring and summer. Hail, damaging winds and heavy rain are possible. Check the /weather/severe-weather-warning/ page before heading out.
Is Illawong weather the same as in the Sydney CBD?
Not exactly. Illawong is inland and slightly elevated, so it tends to be a couple of degrees cooler overnight and can be less humid than the city. Daytime temperatures are similar but can lag behind coastal readings by an hour or two.
How does Illawong compare to bankstown weather?
Illawong and Bankstown share a similar climate, with Bankstown being slightly warmer on average due to less tree cover. Both sit inland, so both avoid the coastal sea-breeze effect that moderates surfside suburbs.
