What is the typical seasonal pattern in Nannup?
Nannup sits in the South West of Western Australia, which gives it a Mediterranean climate. Summer (December to February) brings warm, dry days with average highs around 30°C, though nights can cool off. Winter (June to August) is the wet season, with frequent rain and maximum temperatures often below 16°C. Spring and autumn are transitional, offering mild days and cooler nights.
How reliable are the long-range forecasts for Nannup?
For a town like Nannup, forecasts beyond 7 days have lower accuracy because weather systems can shift quickly. The weather in Nannup 10 days or a Nannup weather 14 day forecast gives a general trend, but always double-check the live forecast above for the short-term outlook. For daily planning, the Nannup weather hourly view is more reliable.
Does Nannup get frost in winter?
Yes, frost is common on clear winter mornings, especially in low-lying areas. Temperatures can drop below 2°C overnight. Cover sensitive plants and be careful on roads near dawn.
Is summer in Nannup humid?
