With today’s live forecast above showing clear conditions, Kearns is currently enjoying a mild autumn afternoon, and the outlook remains stable into the evening, with light south-westerly breezes keeping things comfortable.
What’s driving the weather in Kearns right now?
Kearns sits in Sydney’s south-west, where a high-pressure ridge over the Tasman Sea is keeping the air dry and settled. You’ll notice the temperature climbing gently through the morning before peaking early this afternoon. Overnight, the sky stays mostly clear, which means a cooler start tomorrow — a light jacket might be useful if you’re heading out early. The Sydney weather pattern often influences Kearns, but the suburb’s inland position can make it a degree or two warmer than the coast during the day.
Should you expect any changes tonight or tomorrow?
Not really. The high-pressure system will hold firm through the next 24 hours. You can expect another sunny day tomorrow with a similar high, though a weak trough may brush the coast late Thursday, bringing a slight chance of a shower. For the latest movement, the Severe Weather Warning page stays quiet for now. If you’re planning a trip north, check the Australia weather hub for broader conditions; port macquarie weather often runs a few degrees cooler with more sea breeze.
Does Kearns have its own weather radar?
No, there is no dedicated kearns weather radar. The nearest operational radar is at Terrey Hills (Sydney), which covers Kearns well for rain and storm activity. You can also use the Wollongong radar for detailed coastal scans.
How accurate is the hourly forecast for Kearns?
The kearns weather hourly forecast provided above is updated from Bureau of Meteorology data and is typically reliable for the next 6–12 hours. Beyond that, confidence drops due to local coastal influences. Check back in the morning for refreshed timing.
Is Kearns weather similar to Campbelltown’s?
Very similar. Both suburbs lie in the same south-west Sydney basin, so temperatures and wind patterns are nearly identical. Kearns can be marginally cooler at dawn if fog develops in the low-lying areas around the George’s River catchment.
