Check the live forecast above for South Grafton before heading out. Temperatures in the Clarence Valley town are driven by humid northerly flow off the coast, so expect warm, sticky conditions with a chance of late shower or storm activity through the afternoon.
What’s driving South Grafton’s weather today?
South Grafton sits on the southern bank of the Clarence River, opposite the city centre, and its weather is shaped by the same coastal troughs and inland heating that affect the broader Northern Rivers region. The live forecast above shows today’s high, which will feel more humid if a seabreeze pushes up from Yamba or Iluka. Keep an eye on the Bureau’s radar—the bom radar grafton 512 loop today is a reliable tool for tracking any showers moving in from the ranges.
What should locals and visitors prepare for?
Because South Grafton is low‑lying along the floodplain, afternoon heat can build quickly before thunderstorms develop. The live forecast above indicates the likely timing of any change. For detailed grafton weather trends beyond the immediate outlook, see our Australia weather hub.
Is there a storm risk in South Grafton today?
Refer to the live forecast above for storm potential. If conditions are unstable, the bom radar grafton 512 loop today will show developing cells. Storms can develop quickly in this region, especially when sea‑breezes collide with inland heat.
Where can I check the latest Grafton radar?
The Bureau of Meteorology’s Grafton radar (512 km range, loop view) is updated every 10 minutes. It covers the Clarence Valley including South Grafton, Yamba and the nearby ranges. Access it via the BOM website or our severe weather page.
How does South Grafton’s weather differ from the rest of Grafton?
South Grafton is slightly lower and more exposed to river flood risk, but temperatures and rain patterns are nearly identical to Grafton’s city centre. The main difference is wind direction—southerly changes tend to arrive a few minutes earlier over the south bank.
