Check the live forecast above for today’s conditions before heading out. Sydney’s weather shifts between coastal humidity and inland heat, so pack for both sun and showers depending on the season.
What defines Sydney’s weather through the year?
Sydney has a humid subtropical climate with mild winters and warm summers. The city’s position on the coast means sea breezes often moderate the heat, but humidity can spike in January and February. Rainfall is spread fairly evenly across the months, though autumn and spring tend to be the driest periods.
For the next few days, the sydney weather 7 day forecast in the live panel above will show the pattern. If you need a longer outlook, check the sydney weather 14 days projection, which is more reliable for planning than anything beyond two weeks.
When does Sydney get its worst weather?
Summer storms roll in from the west, often bringing heavy rain and hail in the afternoon. Winter fronts from the south can drop temperatures into the single digits overnight. The sydney weather radar is the best tool to track these systems as they approach the coast.
Does Sydney get hot enough for a heatwave?
Yes. When the westerly wind blows from the inland, temperatures can push past 40°C. The sydney weather hourly forecast will show those peaks, which usually arrive in late afternoon.
Is the sydney weather tomorrow likely to be different from today?
Often yes. A south-easterly change can drop the temperature by 10 degrees in a few hours. The weather in sydney 10 days outlook will show these shifts if you are planning ahead.
What is the best time to visit for stable conditions?
March to May and September to November offer the most settled sydney weather 30 days patterns. Humidity is lower, and the chance of storms is reduced compared to summer.
