Live forecasts update automatically; written guidance last reviewed 23 June 2026 by the Aussie Report 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 precipitation in the Serpentine area; this 128 km loop shows rain bands and thunderstorms moving across the Peel region and into Perth’s south-eastern suburbs, updated every 6 minutes.
What does the Serpentine radar show?
The 128 km radius detects rainfall intensity within about 40 kilometres of Serpentine Dam, covering Pinjarra, Dwellingup and Mandurah. For a broader view, the Perth Weather radar offers a 256 km and a 520 km range—the 256 km live loop captures systems approaching from the Indian Ocean, while the 520 km sweep picks up weather as far as Geraldton and Albany. Any echoes over Serpentine itself indicate rain or hail directly overhead, with colour scaling from light blue (drizzle) to red (heavy downpour).
How reliable is the data?
The Bureau of Meteorology operates this C-band radar, which has a range resolution of 250 metres but can be blocked by the Darling Scarp to the west. Use the perth radar 520km scan for approaching fronts, and the 128 km serpentine radar loop perth for localised storms. Always cross-reference with severe weather warnings before making decisions.
Does the Serpentine radar work at night?
Yes—C-band radar is not dependent on sunlight. It transmits pulses of microwave energy that reflect off raindrops, so the 128 km loop remains functional 24 hours a day, though ground clutter can increase during stable conditions at night.
Why does the radar sometimes show false echoes?
Biological targets such as birds, bats and insects can appear as light green patches, especially during dawn and dusk. The perth radar 256 live feed may also show partial beam blockage over the Darling Scarp, creating stationary returns that are not real precipitation.
Can I see storm direction on the radar?
Yes—the 128 km serpentine radar loop perth shows motion in 6-minute increments. Look for the leading edge of heavy reflectivity (red/orange) moving east-north-east; that vector indicates the storm’s path. Combine with Australia weather hub maps for longer-term tracking.
