Sydney’s weather today, as shown in the live forecast above, brings a mix of conditions shaped by the city’s coastal position. Autumn transitions mean variable temperatures and occasional showers, so checking the hourly breakdown is wise before heading out.
What is driving Sydney’s forecast today?
The live forecast above reflects the interplay between a high-pressure system over the Tasman Sea and a weak trough approaching from the west. This setup often delivers morning cloud clearing to afternoon sun, though coastal breezes can keep temperatures moderate.
- Coastal winds shifting south-easterly through the afternoon, moderating heat
- Humidity typical for autumn, ranging between 50–70% inland and higher near the coast
- UV index moderate to high — sun protection still needed until late afternoon
- Rainfall chance hinges on the trough’s timing; most activity expected after 2pm

When does the chance of rain increase during the day?
