Kojonup’s weather is defined by its inland southern WA location, giving it cool, wet winters and warm, dry summers. The live forecast above shows the current conditions, so use it alongside this guide to plan your day.
What makes Kojonup’s climate different from Perth weather?
Perth weather is moderated by the coast, while Kojonup sits about 260 kilometres inland, on the edge of the Great Southern region. This means cooler overnight lows in winter and hotter, drier summers. Frosts are common from June to August, and summer days can climb above 35°C, though nights usually drop below 15°C. The town receives around 500 mm of rain annually, mostly from May to October, with frequent cold fronts sweeping up from the Southern Ocean.
How reliable are the Kojonup weather 14 day forecast and 10 day outlook?
For any extended outlook beyond three days, confidence drops noticeably. The Kojonup weather 10 day forecast and 14 day versions are useful for broad trends—like a warming or cooling pattern—but day-to-day specifics will shift. For short-term decisions, check the live forecast above or the Kojonup weather radar, which shows approaching rain bands in real time. The Bureau of Meteorology’s official site is the most trusted source for warnings and changes.
Does Elders Weather Kojonup give different data to the live forecast above?
Elders Weather Kojonup sources its data from the Bureau of Meteorology, so the underlying observations are the same. Differences appear in the presentation of the Kojonup weather 10 day forecast or 14 day outlook, but always rely on the most recently updated source shown here.
Where can I see the Kojonup weather radar?
The nearest weather radar is at Albany, about 100 kilometres south. It covers the Kojonup area reasonably well for detecting approaching rain, though it misses localised showers. The Bureau of Meteorology’s website displays the radar loop for free.
How does Katanning weather compare to Kojonup?
Katanning weather is broadly similar as both are inland Great Southern towns. Kojonup is slightly cooler in winter due to its higher elevation (about 300 metres), and frost risk is marginally greater. Summer days are comparable, but Katanning tends to be a degree or two warmer on average.
