Oatley is currently experiencing conditions as shown in the live forecast above. For a suburb on the Georges River, the key factors are temperature, humidity and the chance of local showers moving inland from Botany Bay.
What is driving this afternoon’s forecast for Oatley?
The pattern shown in the live forecast above is typical for a coastal-suburban setup. A sea breeze from the east often moderates temperatures in Oatley during summer. If the trough sits over the ranges, the suburb avoids the worst of the inland heat but stays humid. Check the live forecast for wind direction shifts, as a south-easterly change can arrive abruptly around dusk.
How do tides affect Oatley’s riverside weather?
Oatley’s position on the Georges River means high tide can push cooler, moist air up the valley. This effect is most noticeable in winter and autumn. For the latest on the foreshore conditions, see the oatley tides data linked from the Bureau. The combination of a rising tide and an easterly wind often thickens cloud cover late in the afternoon.
