Check the live forecast above for the most current conditions. Manjimup’s weather is shaped by its inland location in Western Australia’s south-west, bringing cool, wet winters and warm, dry summers – a pattern you can track with the Perth Weather forecast as a regional guide.
What typical weather should you expect in Manjimup?
Manjimup sits about 300 metres above sea level, which moderates summer heat and increases frost risk in winter. The bom weather manjimup observations show average maximums around 27°C in January and 14°C in July. Rainfall is strongly seasonal: most of the annual 900–1000 mm falls between May and October. If you’re checking a manjimup weather 7 day forecast, expect cooler mornings and a chance of afternoon thunderstorms in summer, while winter brings steady drizzle and overcast skies.
How far ahead can you plan for Manjimup weather?
The manjimup weather 14 day and weather in manjimup 10 days outlooks are useful for general trends but lose accuracy after day 7. For longer-term planning, the manjimup weather 28 day forecast gives a broad climate signal (e.g., wetter or drier than average). For reliable daily decisions, stick to the 7-day and the live observations from the Bureau of Meteorology – also available via manjimup weather elders and other third-party sites that repackage BOM data.
When is the best time to visit Manjimup?
Spring (September–November) and autumn (March–May) offer mild days, lower rain than winter, and fewer frosts. Summer can be hot but dry, ideal for hiking if you avoid the midday heat.
Does Manjimup get frost in winter?
Yes. Clear winter nights often drop below 2°C, especially in valleys. The manjimup weather observations regularly record frost between June and August. Protect sensitive plants and check the 7-day forecast for minimums.
How accurate are the 14-day and 28-day forecasts?
Accuracy drops sharply after day 7. The 14-day forecast is reliable for general trends (warmer/cooler) but not exact temperatures. The 28-day outlook is only a broad climate guide; use the 7-day and severe weather warnings for critical decisions.
