If you’re heading out in St Johns Park today, expect a mild and partly cloudy day with the temperature settling near the live forecast above — a light jacket might be handy for the afternoon breeze, especially if you’re planning to be outdoors.
What’s the weather doing in St Johns Park right now?
The live forecast above gives you the current conditions, but here’s the local picture: St Johns Park sits in Sydney’s south-west, so it often feels a notch warmer than the coast. The main story today is the steady south-easterly breeze, which keeps humidity in check. No significant rain is expected, though a stray shower can’t be ruled out later in the week. For a broader look at conditions across the city, check our Sydney weather page.
How does this compare with the rest of New South Wales?
While St Johns Park enjoys a relatively settled day, further south the story is different — Melbourne weather is currently under a cool change, and up north the tropical severe weather warning near Tiwi weather systems is worth watching. Stick with the live forecast above for your local details; it’s the most reliable snapshot for your suburb.
Will it rain in St Johns Park today?
Very unlikely — only a 10% chance of a light shower this afternoon. The sky will be partly cloudy but the bulk of the moisture stays offshore. If you’re gardening or walking the dog, you’re safe without an umbrella.
When will it cool down?
Overnight temperatures will drop to around 14–16°C, so a cool evening is on the cards. A southerly change early next week could bring a more noticeable dip, especially compared to the warmer Sydney weather averages for this time of year.
Is this typical for St Johns Park in autumn?
Yes — mild days with a sea breeze are standard. Unlike the sticky humidity of the tropics (check our Australia weather hub for Tiwi weather comparisons), St Johns Park stays comfortable, with autumn afternoons often feeling fresher than the forecast suggests.
