Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Reef Brief Weather Desk. Data from the Bureau of Meteorology (BOM) and other national met services via Open-Meteo.
The live radar above shows rain and storms moving over Appin using Sydney’s Terrey Hills radar, about 40 kilometres east. The Bureau of Meteorology operates this C-band radar, which detects rainfall within a 256-kilometre radius.
Which radar covers Appin?
Appin sits under the Sydney (Terrey Hills) radar, the closest BOM weather radar for the region. This radar gives good coverage for the Macarthur area, though the Blue Mountains can block low-level showers from the west.
For an alternate view, especially when storms approach from the south, the Wollongong (Mt Keira) radar covers the southern fringe of Appin. Check both radars for a full picture during severe weather.
How reliable is the Appin radar reading?
Radar measures raindrop reflections, not the actual rain on the ground. For Appin, expect a 5–10 minute delay between the scan and the image appearing online. Use the radar in real time, not as a forecast.
Local hills can create false echoes, so contrast the radar with the Sydney weather page for official observations.
Does Appin have its own weather radar?
No. The nearest dedicated radar is at Terrey Hills, operated by the Bureau of Meteorology. Personal weather stations in Appin report rain data but aren’t part of the official radar network.
Why does the radar sometimes show no rain when it’s raining in Appin?
The radar beam scans about 1–2 kilometres above sea level at Appin’s distance. Light drizzle or very low clouds can pass under the beam and not get detected.
How often does the Appin radar update?
BOM radars refresh every 6 to 10 minutes. The live loop on this page shows the most recent available scan. Check the timestamp below the image to confirm recency.
