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.
Check the live radar above for real-time rainfall across the Newcastle region, then use the Bureau of Meteorology’s radar at Newcastle Airport (128 km and 256 km range) to track showers or storms heading your way. It’s the most reliable tool for immediate weather awareness.
How does the Newcastle weather radar work?
The BOM’s Doppler radar near Newcastle Airport sends out pulses of energy and measures the signal reflected back from raindrops, hail or snow. The live radar above shows that data as a colour-coded map, with stronger echoes in yellows and reds indicating heavier precipitation. You can switch between the 128 km and 256 km views—the wider 256 km image gives a broader picture of approaching weather, while the tighter 128 km zoom shows detail right over Newcastle and the Hunter Valley. For a longer look, the “512 km today” loop on some third‑party sites (like Weatherzone’s Newcastle radar) offers a regional perspective.
When should you rely on the Newcastle radar?
It’s most useful during summer thunderstorms or when a coastal trough stalls near the coast. The radar updates every six to ten minutes, so you can watch the movement of rain bands in near‑real time. Keep in mind that ground clutter or insects can produce false echoes, especially in the inner ring; always cross‑reference with the BOM’s text forecasts or warnings for the area.
How often is the Newcastle radar updated?
The Bureau of Meteorology refreshes the base imagery every six to ten minutes, depending on the scanning mode. The live radar above reflects that same schedule, so the image you see is never more than a few minutes old.
Why does the radar sometimes show rain that isn’t reaching the ground?
Radar measures what’s in the air aloft, not what hits the ground. Light drizzle or virga (rain that evaporates before landing) can appear as a weak echo. Check a local rain gauge or the BOM’s observations for ground‑truth.
Can I see rain moving towards Newcastle from the west?
Yes. On the 256 km or 512 km composite views you can track bands pushing in from the ranges or the Hunter Valley. Use the loop feature on the live radar above to watch the motion over the past hour.
