Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Southern Pulse Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
The live radar above shows Appin, in the Macarthur region south-west of Sydney, sitting under the catchment area of the Sydney radar at Terrey Hills. For immediate storm movement, the radar overlay on the map provides the best real-time view of approaching rain or showers.
How to read the Appin weather radar
Appin lies roughly 80 kilometres south-west of the Sydney CBD, near the Nepean River and the Georges River catchment. The live radar above draws data from the Bureau of Meteorology’s Sydney (Terrey Hills) radar, which covers the coastal plain and inland escarpment. Rain bands moving east from the Blue Mountains or tracking up from the Illawarra coast show clearly on this loop. For localised summer storms, the radar’s 512-kilometre range picks up cell development over the Southern Highlands before it reaches Appin.
Are there other radars that cover Appin?
The Sydney radar at Terrey Hills is the primary source for Appin. During severe weather, the Wollongong radar (on Mount Keira) can offer a complementary view from the south, especially for storms that form along the escarpment. Check both loops when a warning is current for the Macarthur district.
Is the Appin radar the same as the Sydney radar?
Yes. There is no dedicated radar at Appin itself. The Bureau of Meteorology’s radar at Terrey Hills, north of Sydney, provides the coverage for the entire Sydney basin, including Appin and the Macarthur region.
Why does the radar sometimes show nothing over Appin?
Radar beams can overshoot low-level cloud or drizzle at a distance. Appin is near the edge of the Terrey Hills radar’s effective low-level range, so light showers may not appear on the loop. The live radar above remains the best tool for moderate to heavy rain and thunderstorms.
Can I use the radar for flood warnings in Appin?
The radar shows rainfall intensity, which helps anticipate rises on the Nepean and Georges rivers. For official flood warnings, always refer to the Bureau of Meteorology’s flood gauges and warnings. The live radar above is a guide, not a substitute for river-height data.
